Frustrated! !!

My husband starts work again today. Spent the whole night sleeping. I understand that he needs his sleep for work but to keep me calm and nice mommy needs sleep too. I do breast feed but thro bottle so its not like he wouldnt be awake just for support. I just fear that now that hes back to work. He will go back to his routine...go to work come home watch a bit of tv (2to 3 hrs) then go to bed. Also fear that bc hes back at work he will think he wont need to help during bed time. I knw its silly but im afraid to bring it up to him bc I am on maternity leave and have all the time in the world.
