I used the routines suggested by Tizzie Hall's book "Save Our Sleep" for babies from birth to two years, it really helped, each age has a different routine and it is all set out in this book.

I really recommend it.
Hope this helps!!! I had to go and buy the "Save Our Sleep Toddler" for my girl as I've regressed a bit with her sleeping habits
Cheers,
Stellajo, funny you mention Tizzie Hall as I used her routine samples as well, when my daughter was 7 months, hardly sleeping throughout the day and still taking her night bottle at 11pm and waking way too early and I had to go back to work.
I followed the routine to the letter and the very first day, she slept through the night and increased her nap time. It was really amazing. She's now almost 2 and doing great, sleeping around 12hr at night (never more) and her nap time is about 1h30 hour. If I ever have another one, he'll be on the routine early on!
