Hi everyone! This is my first post here and desperate for help please!
My daughter is 19 weeks old and has become overtired and upset during the day :(
Basically in the last few weeks i have helped her to fall asleep on her own instead of while nursing. 3 weeks ago she started to have a morning nap lasting 1hr 30 minutes instead of the usual 30 minutes (all other naps are 30 minutes) this lasted 2 weeks and now for the last week all naps have gone back to 30 minutes APART from her last nap which she has around 5/5.30pm which now lasts 1 hour (had to wake her up as she goes to bed at 7.30)
Im guessing this last nap she is trying to start her nights sleep? So she needs an earlier bedtime? If so how to i work this around her naps? 
How do i help her to start napping longer again?
Last night she slept 7.30-12.30 then woke every hour on the hour until 6.30am.
If more information is needed please let me know xx
