Mr. Mom

Does anyone have any advice for my husband while caring for our 3 month old baby boy?

I work 7 am to noon on weekdays and Sunday's 7-3:30 and he watches him during this time. He has to go to work mon-fri after I get home. He says that our LO cries all day unless he holds him and even then he fusses a little. He is fussy taking a bottle and he is exclusively breastfed and before I went back to work, was just nursing. He will go 10 hours with just eating 4 ounces while I am away and that is a struggle to get him to eat that. I have an Ergo baby carrier I thought he can try to carry him in to make him feel secure. Also in the AM I change his diaper, feed him then put him in our room with my husband and he won't go back to sleep after I leave. So my husband has to work until 8- 9 pm then be woken up at 6:30 am by our son so I am trying to think of ways to help him sleep until around 9 am. He sleeps great with me. He sleeps through the night and till around 9 or 10 when I was on maternity leave. Anyways, any tips are appreciated to help with the transition.
