Yeah.... that's a tough one..... Okay, it's not really. I'm sorry, I really do understand the desire to be with your babies, and cuddling them at night is always special, but your husband is right. If you don't make the time for him and you, then your relationship with him suffers, and what kind of home will you be building for your precious little ones if mommy and daddy don't get along? You've got to have that down time to relax and unwind with your husband, and the only way to really achieve that, is to put your babies to bed in their own beds.
If you look at CIO with the right perspective, you can do it. By letting them CIO, you aren't a bad mommy ignoring your babies' needs, you a great mommy, ignoring your
toddlers' tantrums. Your twins are screaming because they know you'll do whatever they want you to do when they scream.
My middle child became horribly spoiled rotten because at around 9 months, my Dad got cancer, and we always went to visit and stay with my parents and I couldn't let my middle daughter ever cry because it made my Dad nervous..... so yeah.... horribly spoiled!!! So she slept with me from the time my Dad was diagnosed, until he died 10 months later. The only way to break her of the habit was to eventually let her CIO. We tried the other methods of staying by her bed, holding her hand, etc.... CIO was the only one that actually worked and worked fast!
Anyway, that would be my suggestion. Your relationship with your husband is too important and it needs to be kept strong. And I'm really big on Mommy getting some down time at night after the kids go to bed..... you'll just feel so much better if you can have an hour or two to yourself each night! Plus, you and hubby will sleep so much better too! And mommy and daddy sleeping better, leads to mommy and daddy feeling better, and being happier, and functioning better, and being a better mommy and daddy for your kids!
