DD is EBF and four months old. She always been an excellent night sleeper - but last night she did a record 10.5 hours! (8.30 - 7.00)). Fed her one v full boob and bit of the other side (now up to express the remainder) and she's gone back to sleep. Will wake her at 9 for next feed.I'm just checking that it is ok for her to sleep so long? Wieght gain fine, nappies fine, alert etc.
