Increased night waking?

Ni

Anyone else’s baby start waking up more often around 7 months? My baby has start waking up every 1.5 hours recently. She is EBF and sleep trained. I don’t mind going in there every 3 hours but every 1.5 is making me LOSE MY MIND 😩 I’ve tried to just wait it out until she falls back asleep but she will just continue crying out until I come in there.
