Hi and welcome to BW, I hope we can help
It might be an idea to start a log of the next few days so we can see a pattern as to what's going on. Do you think you could do that? I'll post a link for some easy log downloads for you at the end.
It sounds like she's not learned to transition through the sleep cycles on her own yet. Typically at 20mims there is a jolt as that's when they go into deep sleep and waking at 45mins could signal she needs a slight push in A times as she can't transition to the next sleep cycle there either. All fixable, don't worry
.
Starting with the first nap is ideal. I would try and put her down around the 2hr45mins mark (average A time link to follow too) and establish a nice wind down routine for you both so she can learn when to expect sleep is coming. Use ssh/pat to settle her initially if she's crying and adopt a sleep phrase like 'it's ok honey, mummy's here, it's time for sleep'. After she's asleep I would do w2s around 15mins into the nap, then again at 35mins. Again, link to follow (sorry for all the extra reading, but the links explain it far better
)
How does she fall asleep at BT? Are you rocking her then too? I think the key might be teaching her to sleep independently, then hopefully she won't rely on you to keep her asleep for her naps for the whole time so you can get some you time in
. I won't lie, there might be some crying but you'll never be told to leave her to cry alone here.
How does that sound to start off with?
