9 month old waking early

Sophia is nearly 9 months old and used to sleep 7 till 7, we were very lucky. But about a month ago this started getting ealier, probably due to getting 4 teeth and a cold and a cough, during this time she also started sleeping more during the day, she has never been a big day sleeper before! About a week ago I relised maybe she was having to much sleep during the day so it was affecting her night sleeping. Her rountine is usually:

Wake 5-6, get up at 7
Breakfast 7.30
Milk 9.30
Bed 10 till 12
Lunch 12.30
Milk 2.30
Bed 3.15ish till 4.30 (if not awake I wake her at 4.30)
Dinner 5
Bath at 6
Milk 6.40
Bed 7

Is this to much sleep during the day, has this happened to anyone else, is it just a stage?? I would be more than happy if it just went back to waking sometime after 6. I just can't stand it when there is a 5 on the clock!! Sorry for the ramble!

It doesn't sound like too much sleep to me, Its what I try to get James to do. I always heard that sleep begets sleep, so in essence the better she sleeps during the day, the better she will sleep at night.

I do think they go thru stages, my boy isn't the best sleeper, but he does swing from sleeping really well (8-7), to waking in the night. Its sounds like you need to train her to go back to sleep, maybe by just ignoring her and leaving her in her cot until 6.
