My dd (2.7) always needed loads of sleep as a baby- 15 or 16 hours a day. She still sleeps around 12/13 hours a night, and has 50 mins nap. I know a bf baby isn't supposed to go that long between feeds though, ff is slightly different, the length between feeds doesn't seem abnormally long.
Is this normal for her? DD always slept more when she was coming down with something (cold, ear infection, whatever)
