Mazz, I have also heard that many lo's can't handle very long A time in the a.m. I girlfriend (who has never had sleep issues) has a 12 month old who does very well with only 2.45 - 3 hours before his first nap. Sleeps like a champ morning, noon and night. Not that a shorter A time is what does it all but just an example of a 12 month old not doing well on 3.15 of A time in the a.m.
If dd wakes around 7 her first nap is at 9.45 and she is 9 months old. As the day progresses she handles a long A time better until the evening where if her p.m. nap was no good she can easily handle 3.5 -4 hours if need be. Every babe is different but its just a thought.
I have spoken with a moderator (who lives very close by) and we figure dd's waking between 4 and 6 is hunger. I am definately NOT a BW expert, far from it but this is our schedule and I like it alot and for the most part of the week it all goes well.
7 wake
9.45 nap
11.45 wake
12-12.30 ish lunch
2.45 - 3 nap (Oprah's on) works very well for the time being!!
4 - 4.30 wake
7 get ready for bed
7.30 lights out
Every babe is different but its just a thought.
