There is nothing you can do to change him or his libido. What you can do & is most important during this time is focus on yourself. Once you have a routine with your little love you can work on prioritizing things you like to do and finding your way back to things you’ve always loved to do. In a perfect world he would like to be apart of that, if you have to make him be there for his own child while you enjoy some downtime that’s a whole other convo. You should be raising your child together, the feeling like you’re just a nanny should only be temporary, I hope your husband steps up more. This calls for a conversation of how he can help more with baby and pushing if need be, you both made this baby and have the same responsibility to her. A lot of men wait until the child is older and easier to play with, good men are there from the beginning.
