Hi Victoria
Teething and crawling are developmental issues that can really affect sleep routines. So it could just be a phase.
However after reviewing your routine, my initial impression is that your LO is probably OT by the time she's put to bed. Do you think this could be the case? At 9 months, most bubs still need 3 hours sleep per day (some more, some less - this is just an average). It can be split a number of ways:
1) 2* 1.5 hour naps (9.30-11.00, 2-3.30, bed at 6.30/7) This works for my DD who is 9.5 months
2) 2* 1.5 hour naps (9-10.30, 1-2.30) + an afternoon bridging nap (4.15pm for 20 minutes)
3) 45 min nap (morning and afternoon) + 1.5 hour lunchtime nap
I also started to re-swaddle my DD once she started crawling - more as a sleep training device - just to keep her still in her cot so that she could fall asleep.
Another tip I've picked up is to try not to feed your LO before 6.30 am - as their bodies start to prepare for this first feed one REM sleep cycle prior (ie. 40 minutes before 6.30am). So if you're feeding at 6.15 - then your LO will be starting to stir just after 5.30am.
This is my routine:
6.30 wake
7.00 BF
7.30 Solids
Activity
9.30 Sleep for 1.5 hours
11.00 Solids and BF
Activity
2.00 Sleep for 1.5 hours
3.30 BF
Activity
5.30 Solids
6.30 Bottle and Bedtime
My DD was a terrible day time sleeper - but this routine has really helped day and night sleeps and she doesn't fuss/scream when I take her into her cot anymore.
Hope this helps...keep us posted on what's working/not working for you.
