7 month - waking up out of habit?

[Jpstar]

My 7month old has been waking at the same time every night, and will only go back to sleep with a bottle. We can get them to sleep but will keep waking every 10-15 minutes until they have a bottle, and then will go back to sleep the rest of the night. They can self soothe for naps, bedtime, and sometimes will see them wake overnight but will go back to sleep.

how do I know if they’re waking up out of habit? Or if it’s hunger/regression?

What time is the wake up? I would have thought one bottle overnight at 7months old isn't the end of the world? They are still a baby. Especially if they are sleeping either side of the bottle?

Is your concern that you want them to just sleep all the way through the night? If the wake up is 1am you could try waking them 15mins earlier and see if you can edge the feed back to 11pm for example if that feels better for you, if not just feed them when they want it won't last forever
