My husband is one of those guys that can be super critical, and really just want things done quickly and 'easily' in his mind. For example, we have a now almost 2.5 year old who had many issues in the beginning until about a few months ago. He had reflux, milk intolerance, was sick constantly, etc. thus causing NO sleep, eating issues, etc. After 2 sets of ear tubes and finally and adenoid removal things have improved a little and he 'mostly' sleeps through the night as of 3 months ago! yay! we still have our struggles but things have improved tremendously. All of this though has cause a lot of turmoil with my husband and I... he only wanted to listen to his mother's constant 'opinions' about how I am spoiling our child, he needs to cry it out, etc. instead of listening to me or the doctors. Things got pretty bad for a while but then improved. We are now pregnant again and due in August but the old behaviors are coming back and I need help on how to communicate better with him or if any of your spouses/partners are the same? He is now harping on the fact that our son still has a paci and blankie he sleeps with... in my opinion so what? It doesn't hurt him, he has great speech, and hell it helps him sleep! He is not going to have it when he goes to college. Long story short, I got super mad last night because his mother had called and said she wanted pictures of our son without his 'dumb' paci when she comes out to visit and my husband threw in the fact that he doesn't think our son should have it anymore, etc. then that turned into me also finding out he bragged to his mom about how he was up with our son the other night and got him back to bed (mind you this is only the less than 5th time in our son's whole life he has gotten up to help me. Otherwise he just critiques from the sidelines without helping). Sorry I am just super frustrated, hormonal today, and truly thought we were on a turn from the times we had with our first son. Ps isn't his mother a gem? I could share more but that's the short version of how she is all of the time.

Re: Advice on communication with partner
You need to sit down with him & tell him how you feel. That you want more help & need his support vs. Back-seat parenting.
Personally, that would infuriate me that he wants to supersede your authority as Mother in favor of his mom's opinions. She raised her kids her way.
It's up to the two of you to figure it out yourselves free of others' butting in. I agree with you about CIO & pacifiers.
My 3 year old still has her pacifier & my MIL tries to tell us what to do with things too. I tell her that it's not up to her to parent our child. We make those decisions & we are working with our individual child's needs. Not every baby is the same.
What's funny is that she tried to blame DD's speech delay on the pacifier. Both language pathologists, & therapists have said it doesn't matter.
DS is speech delayed (just like sister his receptive language is amazing) & he never took a pacifier.
Basically you two are the parents. You need to assert yourself & your husband needs to be more active.

I don't know you or your situation but it sort of sounds like you are super pissed and possibly exaggerating how bad your H actually is. Perhaps I'm giving him the benefit of the doubt because I hate when my H disregards things I want to do with the kids because his way is the right way (discipline for example).
You are both the parents so you have to work together to find a happy medium with little things like the paci. I personally wouldn't want my 2.5 year old to have one but it's not that big of a deal - except to your husband, so perhaps hear him out.
I do think you need to make it perfectly clear that you don't appreciate him running his mouth. Be open and honest with him.
As far as his mother goes...tell her to butt the fuck out (in a polite way). Stand your ground and continuously tell her that you don't appreciate the comments. End that shit real quick.
Secondly, if it were me, I would openly tell my partner that if he truly has a problem with the paci thing, then he needs to help out with whatever it entails to wean the child from it. (By your description, it sounds like your partner isn't helping you out as much as he should, only having helped out 5 times if your son wakes up at night in 2.5 years??). I would tell him that you can't be a backseat father, if you have a problem, then you need to get involved and help with the resolution.
