It might have been mentioned already but I'll weigh in with my opinions:
- routine, routine, routine (sleep, feed and play) Same times all the time.
- help as much as you can, especially if you can do the latest feed possible with a bottle so Mom can sleep
- give Mom a break. Being home all day basically alone with a baby latched to your chest is probably one of the most emotionally draining things a person can do. Pair that with crazy hormones and sleep deprivation and you have a recipe for postpartum depression.
