13 month old false starts every night
Please help. 13 month old somewhat sleep trained. Falls asleep independently after 5ish minutes of crying and sleeps for 40-50 minutes then wakes up and cries for anywhere from 5 minutes to an hour. We used to nurse her back to sleep after the first wake, but stopped about 2-3 weeks ago and have been letting her CIO but it doesn't seem like it's getting any better.
Bedtime: \~8pm
Wakes up to nurse once nightly around 1-3am (this is fine with everyone in the home and we're not interested in fully night weaning unless we need to)
Day wake: 7-7:30am and we almost always have to wake baby up
Wake windows vary. Roughly 3.5/3.5/4 if 2 naps, but some days she only does one nap. We always aim for at least 4 hours awake before bed. We cap daytime sleep at 2 hours total. Baby is not nap trained and most naps are contact naps.
Any ideas for how to stop the crying at bedtime and especially the waking up after one sleep cycle? Happy to provide additional info...ask away. Thank you.
