How can I get my husband to help me with our baby

Alright, ladies. I need your thoughts on this. My husband and I have a 8 month old daughter and I'm pregnant again I'm currently 11w5d with my first pregnancy after she was born my husband would help me, no problem.

But now it's a chore having to ask him for help. He doesn't doesn't give a bath to our girl, doesn't help me with changing diapers or anything. The only thing he would do once in a while is give her a bottle. Besides that I need to ask countless times for him to help and I'm honestly just losing my patience with him. Other times, he would see that our girl needs a diaper change and while I'm on the kitchen he would just tell me "come change her diaper" I would reply "I'm coming, just let me finish this." And take my sweet time, but once I'm done and check up on her, her diaper would still be super wet and I would be the one changing it.

He tells me that he is going to help me more once baby #2 arrives but I'm really doubting that since with this one he doesn't really help me anymore. I have to understand that he works 6 days a week from 8am-7pm and once he gets home he just wants to chill on the sofa and that I'm staying at home to take care of her. He provides everything we need and I'm super grateful for that.

This seriously has taken a toll on this relationship. I no longer want to have sex with him, since at the end of the day I just want to throw myself on the bed and not have to do anything for a couple of hours.

He is everything I could've ask for in a man, but I'm honestly at the last straw and don't know how much longer I can keep pretending to be happy-go-lucky when I'm just super depressed thinking about this that goes on everyday.
