so TWO female in laws decide to tell me that taking care of my two are "not that bad" ... because 1 babysat her friends kids ... which are about 2 yrs apart and the other had two children about 1.5 yrs apart ......

yeah taking care of two kids IS hard ... PERIOD ... but twins, SAME AGE .... harder!
what good snappy comeback should I throw at them next time?
just pisses me off to no end! 
Re: it's NOT the same (vent)
Ah, that's happened to me, too--people don't think it's that hard but then when they offer to baby-sit, they want to bring a friend. :P
No, twins the same age isn't bad at all compared to kids over a year apart. I mean, just because one can feed them self or entertain them self while you tend to the other doesn't make it one bit easier. Well, except for maybe anytime the twins are awake and you are watching them alone. But other than that, yep, piece of cake.
::wipes up the dripping sarcasm::
First of all, I'd tell them that BABYSITTING any kid, 1, 2 or 3. Twins, singletons, what-have-you is worlds easier than actually PARENTING the children. So, right off the bat they are wrong!
Then, I'd tell them they should try it. Alone. Have each one babysit on her own during a time when the twins are awake, needing a diaper change and starving. Oh, and in need of nap--see if they can get them both to sleep at the same time .
. 
Other than that, not much you can do other than smile and nod. And think to yourself, "Idiots!!"
This is always such a stupid argument. Why does one have to be harder than the other? And why do you care?
I think two small kids of different ages could be harder but try telling that to the MOMs "We've got it so rough" brigade. Too many MOMs are so wrapped up in the idea of how hard they have it (whether or not that is true) that they get stupidly defensive and blind to the fact that other mothers may have some tough times as well. For a number of reasons.
Too many variables. Maybe the twins are low-maintanence....maybe one mother is able to handle things better or worse than the other?
Who knows and who cares? Why waste your energy seething with self-righteous anger and plotting babysitting revenge? Just smile, be happy and let it go.
I get that all the time too and it really used to just drive me up the wall.
But funny thing is no one can watch all my kids at once. In addition to my almost 9 month old twins, I also have a 2.5 year old DD.
My MIL comes down to so call "help" me - and she just sits on the couch. She tells me everytime that we should go out to dinner while she is here.
Umm hello she can't even handle my DD by herself, how is she supposed to handle 3 moving kids!
I recently heard from my SIL that she had it worst them me when she had her kids. First of all she had 2 - I have 3. When she had her second son, her other son was 5 years old. My DD was 20 months old when the boys were born.
Her reason that she had it harder. They only have 1 car and we have 2. Yep! Like I go anywhere anyways. It is just two hard some days to get out of the house so we might as well have 1 car.
People just don't have a clue!
I just ignore them, cuz the fact of the matter is I know the truth!
I must say, it is getting old to see almost this same post title every few days...
I'm sure my life with be a complete chaotic mess with 4 under 4, but it's MY mess and I'm just going to be thankful to have been blessed with the gift of fertility and the joy of babies : ) Yeah, it will be nuts, no arguing that. And harder than anything I've ever done. No one except us MoM's will ever understand what it's like to be a MoM, but I'm sure everyone else has a difficult part of their life that I'll never understand either. (I have a very supportive, helpful hubby who is my best friend, we have our health, a stable job, healthy kids, etc. There are other situations that could be very difficult to deal with too. I'm happy that having a bunch of young kids will be my major "difficulty"!!)
MiaVonT... I should clarify that my last post is NOT directed at you! I do feel very bad that your friends feel the need to belittle your situation. That's just not acceptable.
I just get tired of mom fights in general: working moms vs. SAHM's, breastmilk vs. formula, CIO vs. anti-CIO, etc. etc. etc..... It wears on my emotions after hearing so much of it! It's sad that someone always has to be "right".
