Try not to let her be awake any longer than 1 to 1.25 hours after each waking. Any longer than this and she will get overtired and have a lot more difficulty falling/staying asleep. After an hour or so of being awake, can you try feeding her to sleep in a darkened room? Rocking her back and forth in the pram (she may be more amenable to this if you catch her 'sleep window' by watching the time between naps)? White noise during the above? Some people swear by swaddling in combination with some/all of the above?
My baby gets very tearful for no reason (ie ruled out feed, nappy etc) a few hours after waking and I assume it's tiredness as a nap a few hours after waking is suggested. How do others encourage naps? I find it very difficult to leave her to cry herself to sleep but the failsafe option of her falling asleep in her pram out walking isn't always possible (today we have a GP appt at 1 so need to get ready for that) as it's a faff to do (3rd floor flat). any advice for settling for naps appreciated!
