Just after a bit of advice. Have a 17 months old daughter who has always napped well but nights have been hit and miss. She currently has an hour and a half in the afternoon but then is awake over night for anything from half an hour to two hours. Few days ago she only had half an hour nap all day and slept for 12 hours overnight. Just got me thinking is an hour and a half too much? Most things you read say two hour naps but I’m not thinking is she having too much day sleep?
