First time mom.

So I have a 6mo and she was doing great for a while. But now all she does is cry constantly, she goes to bed for 30 minute intervals, when usually she sleeps for 2 hours during the day and 7-8 hours at night.

I feel like I’m back to dealing with a newborn and I really don’t know what to do anymore. I’ve tried everything i could think of.

She has a doctors appointment tomorrow, but I feel like they’ll say it’s normal. But that’s not how she acts. She won’t even play with her toys. She just cries.

Any suggestions?
