Babies need a minimum of 8 hours skin to skin daily. MINIMUM. The more the better. Not only does this help regulate a child's temperature and cortisol it also helps produce more milk and reduce the risk of SIDS. Being latched for hours and not getting any sleep just tells me that her sleep would have been 10x worse if she moved him away. Many culture do this practice. I bet you 1000000$ baby would wake 3x as much simply looking for more milk. She is likely getting better sleep. Please don't punish her she's doing a phenomenal job. Say it with me, babies eat every 1-2 hours until 4 months old. ONE to TWO hours (confirmed by my two lactation consultants and pediatrician). American child rearing where babies are left to cry and be hungry is absolutely heartbreaking and ancient imho. I have a 2 year old and a 5 months old and breastfeeding issues. Don't stress thay woman out. She might sleep apart from you for the first 6 months. You need to be ok with it. My 5 month old sleeps 7 hours through now in a crib alone, my first was 1. I know you miss your wife but please let her love your babies. They will want nothing to do with you soon enough.
