Idk maybe my advice isn't solid cause I don't have kids. But. It's important to make your partner feel good regardless of what's been going on around you. I 1000% understand that your entire world was 360ed, and that you may not feel turned on enough for sex. But, I do think there are some steps you can take here. Personally from what I've read on here 5 weeks is too soon for sex. But my stepmom also once told me she had sex with my dad as soon as she possibly could after her babies. Here me out, try to make your husband feel wanted and valued. A lot of times sex is one of the only ways a man feels loved. Some men think sex is love which is ok. My husband reacts similar when i go on a no sex streak, he doesn't feel desirable when he is turned down and always thinks the worst(that he doesn't turn me on or that I don't want him etc). Maybe don't have sex but at least try to do something for him. By the sounds of it it's been longer than 5 weeks without sex? Maybe try giving him oral till he finishes? I purchased a little pocket pussy thing for my husband, he really likes it. When I want to give him oral and finish him fast I'll use that on him at the same time. It's a lit smaller than a flashlight it's super super tiny probably like 4 inches or so. If you have a vibrator, it should be ok that he has a toy too. Definitely get him a toy if you can! I was a little uncomfortable with it at first tbh , not gonna lie, but I realized that a toy can't replace me and that I have dildos and vibes. He has to feel wanted even tho you guys just had a baby. Babies are one of the biggest stress factors in a relationship, kids in general. Which is why it's so important to make your partner feel wanted(more than just sexually). Because once stress is involved it's super easy to lose track of what's important and get in a new cycle of being bitchy towards eachother. You guys are only human. If you're up to it, when baby is asleep Maybe make him a nice dinner or run him a bubble bath, soak him up real good down there with a handy or just something special for him in general. They gotta feel special too. Hope this helps some
