my 18wk DD1 is a good sleeper, but if i leave her on her playmat for longer than 20mins i'll find her sucking her fingers and going off to sleep. this is only 45mins after having a nap. she's having regular naps - 1 in the morning, big 2.5hour in the middle of the day, then another in the afternoon. she sleeps from 7pm-10pm, then 11pm through till 7am, but lately has been waking up to play at 3am but goes back to sleep very quickly.
i'm feeding her 6fl oz 5 times a day. she's a big baby - haven't had her weighed for a month but she is definitely over 16lb. she's really active and is constantly on the move and making loads of noise. can only think that she's wearing herself out or that i'm underfeeding her?
any thoughts?
