Re: work 4 days/wk for 10hrs/day
Nurse for as long as the baby wants. More nursing is better, even if the baby is "only" comfort nursing. The more comfortable the baby is at the breast, and the more he turns to the breast to get his needs for cuddling and nutrition and sucking met, the better breastfeeding is going to go.
At 3, almost 4, months, it's normal for a baby not to fall asleep after nursing, though many continue to do so.
Baby should be sleeping about... I think it's around 12 hours total at this age...? But those hours are not in a row! Many babies will cat-nap throughout the day, 20 minutes here, 20 minutes there, and sleep for short 1-3 hour stretches during the night. At no point during the first year should you expect your baby to sleep longer than 5-6 hours without nursing.
