Routine. Please help!

[arttisahn]

My 7.5 month old baby has no routine. He had a perfect routine until teething started. He now goes to sleep at 22:00 or after and wakes at 7:30. He has the usual 2-3 short naps a day at roughly the same time. His sleeping pattern is consistent but the times won't suit when I go back to work.

I'm really struggling and need help to change his routine as stress free as possible. I'm a lone parent and doing this first time on my own. Feeling a bit lost!

We've not really had a routine, but now at almost 8 months it seems to be naturally developing. It's not always the same, but it goes something like this :
7ish wake
8 solids
9 nap {usually only 30 mins, but sometimes longer)
10 milk
11.30 solids
12 nap (about an hour)
1.30 milk
3 nap (about an hour or an hour and a half)
5.30 solids
6.30 milk
6.45 bath and bed about 7 or 7.30

Not sure this routine will be great when I go back to work either but I am hoping by then she'll be able to stay awake a bit longer and so will be ok with the nursery!
