Hello everyone!  I rarely post on here but I regularly check up on the conversation and progress of all our pregnancies!  Congrats everyone on our journey 

So I'm sure similar topics have been posted but I'm so irritated.  I've been agonizing on how prepared to be for baby with clothing and diapers.  I've read all the posts on here of what has been most helpful (thank you for your input to us ftm's!) and decided I'd rather start with the NB/ 0-3 month sizes for onesies and clothing and go from there to account for how much our son will grow (or how slow he'll grow for that matter). Plus, I'm a "please get us what we need if you want to get us a gift" kinda gal (hubby's the same). (I didn't even know how many packs of onesies to put on there to be stocked up!)
We finally register and send out a mass text to inform people about the shower and where we are registered.  MIL posts a text in the group text saying she looked at our registry and said 'you may want to consider having larger sizes for clothing', gave me a formula to account for growth, and even had the 'I think most mothers will agree' phrase in there. Oh and 'just a thought to consider'.
I tried to sound polite but wanted my point across. I said 'we decided we want newborn and 0-3m sizes to accommodate to his growth.'  Also said I'm most concerned about being prepared for the first three months because we have nothing prepped (except for furniture type stuff and some diapers and wipes). I didn't say this in the text but both of us get overwhelmed in how much to be prepped for baby.  I said in the text (which yes may be snarky) 'but if people want to get larger sizes they can'. 
I'm frustrated because she knew we were registering and could have told us that moons ago instead of in a group text AFTER we registered.  And, I appreciate the advice but at same the time that's how my husband and I decided to start preparing for baby.  I don't want to have all this unused clothing because people over bought for us, or have to wait to use the clothing when we need the smaller sizes before the bigger sizes.  She could have politely asked me about bigger sizes 'oh I see you didn't have any, can I ask why?' instead of basically suggesting I did it wrong and/or go back to add things because she suggested it. 
Besides, what we REALLY want help on (even if it's gift cards) are the bigger, expensive items or even grocery gift cards since we'll be on limited income during half of maternity leave.  (I've tried to go for the grocery store gift card idea but apparently it's too non-traditional). 
Anyway,  I just wanted to rant where people will understand where I'm coming from.  My aunt (love her dearly) told me to quit worrying. I said "I'm not worrying I'm irritated but I'll stop talking about it.'
I care for my MIL, but this is a handful of times where she had crossed a boundary with me, when she simply could've asked more politely which in turn shows my methods are respected. 
Rant over, and thanks for listening! (Btw, at the time I have terrible aches and pains which are making me irritated and crabby more often than I'd like.  Isn't sensitivity to the pregnant woman with things like showers and advice common sense for women family members before us?)                 
 
                
Re: MIL + Baby Registry = I'm irritated!
And btw I think it's rude to try and dictate (even though you said they can get bigger clothes but even you said you'd said it rudely) what people buy you. Especially since most people don't shop from the registry anyway.
I do realize and completely understand not wanting random stuff that you may not use hanging around - we got a lot of that and I either gave it away (quietly, after thanking the person) or exchanged it when possible.
And grocery gift cards is a far reach ... people want to celebrate your baby - not feed you. Accept the gifts you get so you dont have to buy stuff and use your own money to buy your groceries.
It was probably best for her to give you some really great motherly wisdom outside of a group text... but I ultimately agree with your MIL.
It can be frustrating when other people are telling you what to do, but getting bigger sizes, especially in bodysuits and such can be a big blessing because you never know how big they will get in a certain time frame.
For what it's worth, I'm having the opposite problem. People are only buying us newborn/0-3 month clothes and there is no way baby girl can wear it all! Just smile and say thank you and don't tags off! Return/exchange what you can and use/donate the rest!
Did you send out invitations for your shower is was it just through text? I also think it's pretty rude to suggest what people buy for you.
I am frustrated about how she presented the advice and the timing that she did. Others in my family who know my MIL agree that it wasn't appropriate how she presented her advice. It was a mass text because at the time of invites we weren't registered yet, so I sent basic 'we are registered at target' text with no other info about what was on it figuring people will be asking me soon anyway.
I know registries are a guide, which is why we didn't go overboard on clothes in the first place. We didn't put many clothes on there because I figured people would buy according to what they thought was cute and wanted to get. Plus, it will be wintertime when baby is born and they still had a lot of summer stuff out. But, I assumed the registry would be a ballpark of what we are looking for anyway. Because of her advice that's why I said "if people want they can get us bigger sizes."
I was just really frustrated at the time I got the text after having just registered.
For what it's worth, it is sound advice - baby can wear onesies even in the winter, while just inside and around the house, and, in most cases, 0-3 month does not literally translate to being able to wear it for 3 months. My first was in 3-6 months after just a few weeks (mostly for her length - she was a loooong baby!).
However, I do remember being annoyed by pretty much everything my MIL said and did with my first pregnancy... Has been smooth sailing this time, but I don't know if she's less annoying or I'm just more laid back. Haha!!
The whole mass text response is really what bothered me down to it.
And, as mentioned I'm at the point in pregnancy where physical pains are preventing sleep, even with approved sleep meds. Work stress has been very high of late, so my skin is more thin than I usually let it be.
Also, please don't think I'm a selfish jerk. I am super thankful for anything anyone wants to give us, and for all the love and support. We have had a ton of changes (good and bad stress) since pregnancy so emotions have already been everywhere.

PS mass text are the devil. Lol. I hate group text, also!
I could have text her in private with my response. But like I said, I was irritated in the first place as she has a habit of doing that. Afterwords my step sister and an in law said it was manipulating, but I handled it well.
Anyway, I do appreciate the advice about clothing. It's been difficult trying to figure out how to plan. I take the suggestions and try to figure out what I like best.
