please help with constant waking

[florida2001]

I have 9 months old, still breastfeeding her and she is on 3 solid meals. she goes sleep between 7-7.30 pm and sleeps until probably midnight, waking up screaming. I pick her up breastfeed her and she goes back to sleep. she is then up at 3 am and I do the same. at 5-5.30 she is up and she is ready to play. I am so tired. I have 6 year old and I do not want her to wake so thats why I pick her up and breastfeed . She has good dinner every day around 5.30-6 pm so I dont think she is hungry. she falling asleep when breastfeed her but putting her to crib while she is still half up.
please advice how to make it better.
Her first nap is at 8.15-8.30 and takes between 1-2 hours
the second nap is around 1 pm -1.30 and is around 1-2 hour it depends. so basicaly between 2 nd nap and night sleep she is up feom lets say 3 pm until 7 ish.

Night wean and this:

I would move everything around and everything later. It takes a few weeks sometimes for Los body to realise to sleep in. So something like.

930am to 1030am. Wake from nap. Mean I know. But, the theory is letting lo sleep as long as they like at this nap is allowing them to catch up with the early waking.

130pm or 2pm, depends on your lo awake time till 330 pm or even 4 pm if needed.

Then bed between 730pm and 8pm.

I know getting that first nap to 930am is a hard slog. But move it 15 minutes each day; every 3rd day, move it 15 minutes forward again.

A later bedtime did help move to a later rise in the morning with my lo. Also capping first nap.

I think the sole cause of the waking is that she is fed to sleep. I don't think she is waking due to hunger, the wakes are because she's struggling to link sleep cycles and needs to comfort sick to resettle.

Theres two quite different approaches to this

(1) Embrace the fact that you feed to sleep. Find a way to make cosleeping work, rather than it being a battle. Stop trying to get her to sleep independently. Allow her to sleep with you and sleep with your top off. She is old enough to find her own way to your nipper and feed without disturbing you very much.

(2) Completely separate feeding and sleeping. Move the bedtime feed to be downstairs, before bath or getting ready for bed. Then use a different method to get baby to sleep (and accept this will involve lots of tears initially). Likewise, stop feeding at night completely, all in one go. Again, accept there will be tears and just find another way to get her to sleep.

Don't night wean or do controlled crying, it's emotionally scaring. It's the 8-10 month sleep regression. It will pass.
