Milo was sleeping about 8 hours at night at 8 weeks.
From 5 weeks - 12 weeks it was about the same no. hours as his age in weeks. I think he started slleping 4-5 hours at a time from day 2 home from hospital a couple of times a day, but that was conter blanaced by 5-10 hrs of awake & unsettled time in the afternoons
