this is all my 3 month old wants to do.

Sh
She was sleeping through the night and now she's waking up to be on boob several times a night. I don't even know if she's eating every time. She just wants to be on me. I'm trying to clean house and she cries now until i put her on boob. Lol I feel kind of tired and sore! It's gonna pass I know. But is it normal at this age?? Or what????
