Hi there, Esther has a good point about extending the naps. That is part of EASY..and when that is mastered(so to speak) then other things will fall right into line. Work on extending the naps. If you are noticing a pattern about when your LO is waking ie after 45 min etc..go in before that time...and help your LO into the next sleep cycle. Do you have any of the books? I know in the 1st book it gives great info on the sleep cycles..helped me tremendously!
So, ya...help Lo through to next sleep cycle either by placing your hand gently on your Lo's back and rubbing or shhing....if your Lo wakes up before the nap SHOULD be over. Then as Esther said use pat/shh or pu/pd (have you used either before?)to assist your LO back to sleep. If it comes to the point where she is due to eat (3 hour mark) then I would feed her, change her and attempt to put back to sleep once again using pat/sh or pupd. If you need help on those 2 things....pat/sshh ot pu/pd check out that forum as it is great.
If it gets to be too much for either of you...take a break for a few min..leave the room etc..and go back in and try after.Again, the book has some milestones in it that gave me the courage to continue. Cause it can be tiresome!
HTH!
