Sleeping problem

Beebee

Was sick and later congested we are almost over it and the Leap now 7months, I'm not even sure if it's still going or over. Teething for about 2 months, we are still waiting for the top 2.

Every hour she tosses, rubs eyes, starts crying. If I'm not there nursing it'll escalate very quickly so not sure if CIO is right for us. She nurses for 3min. Then goed back to sleep. Eventually she gets gassy assuming she's drinking a lot of the foremilk.

I'm co-sleeping for a month now. The rubbing the eyes started after the congestion, probably sinus issue I'm not sure. She has discovered her thumb at 3 months but right now she barely uses at sleep.

What kind of sleep training should I start?

I don't know if I'm doing the right thing by co-sleeping and nursing to sleeping.

Any suggestions????
