Hi & welcome to this site
,
How does your dd fall asleep? I believe she is overtired & needs more daytime sleep. When she wakes from her morning & afternoon nap (be it earlier than 1hr) what is she like... crying or happy to be awake? If she wakes happy that could be an indication of her needing more A time before a nap. Most 6mo's should be able to handle 2.25-2.5hrs. The morning & last A time (before bedtime) is usually shorter than other A times.....so her day should look something like this:
8am - wake for the day & breastfeed
9am - breakfast
10-11.30 - morning nap
11.30-12pm - breastfeed
2-3.30pm - afternoon nap
3.30-4pm - breastfeed
6-6.30/6.45pm - catnap
bath/bedtime routine
8pm - breastfeed & bedtime
So I would suggest adding 15mins or so to her afternoon & evening A time until you are close to 2.5hrs. In the meantime, I would put her down for the night earlier... often an earlier bedtime (when a baby is overtired) stops the night wakings & lets the baby catch up on some sleep.
If she has only napped for 1hr then the afternoon nap needs to be bumped up, so does the catnap & bedtime.
This is all of course considering she does not fall asleep with a prop (like a dummy) & NEEDS it to get back to sleep... in which case you will need to think about eliminating that association & weaning her.
What do you think?
