I need advice.

Hey ladies. So, I want to believe this is normal, but I don't feel like it is. Every night when my daughter wakes up I get up with her, I get up every morning with her at 630-8 am. And my husband sleeps until 10-11 am. And when he does wake up he doesn't help with the baby unless he is asked too. Which ya I kinda expect that. But I can't go take a nap because I'm scared she won't be taken care of if I do. And honestly this is scaring me when it comes to TTC. Like am I gonna be able to handle this when I'm exhausted as is?? He is pushing so hard for another baby because my daughter isn't biologically his. *AND FOR ANYONE ASKING NO HE DOESNT WORK.*
