6.5 mo waking multiple times a night HELP

Kc🧜🏼‍♀️ • mj7/23/19🦋🦄

FTM here..My daughter is 6.5 months old.. at 2 months she slept thru the night perfectly! Then at 4.5 months she started waking up again, but only once in the night. Now she wakes up 2-3 times a night and it’s killing me! I am sooo tired! She sleeps in her crib in our room. But honestly that 2nd or 3rd time I end up just throwing her in the bed with us bcuz I’m so tired. She also doesn’t nap well. She will fall asleep nursing, then wake up as soon as I try to move her.

Lastnight I pumped a little breast milk and added the baby cereal oatmeal to the milk and spoon fed her some before bed. She hated it, but I was able to get a little down her.

But it didn’t make a difference with waking up.

Which brings me to my second question..

I feed on demand, so usually during the day she goes about 3 hours before wanting to nurse again. I do give her some baby food between feedings. I know this isn’t about really EATING more getting use to eating. But is it possible my daughter has day/night feedings switched? Bc it feels like I’m feeding her more frequently at night now 😣

Help please!
