🐾GiGi🐾
I had my son on Wednesday. We were having the best time breast feeding for the first 24 hrs. Then the day 2 cluster feeding started. This kids been latched for going on 4 hours there's no freakin way he's this hungry but he screams when I unlatch even to burp. This is my last night in the hospital. My eyes are crossing I'm so tired. How do I get this madness to stop?! Someone help!
