DD (10 weeks) is crap at napping during the day (see separate thread here). On the odd occasion where I have managed to put her down, she gets to the magic 45 minutes and I then can't get her back to sleep. She seems to go from sleeping to screaming (and I do mean screaming, not sleepy noises or grumbling) within a matter of seconds so she's proper awake. What do you do to get your bub to carry on sleeping? Will she eventually learn to sleep longer without my help?
