Scream crying

Vanessa

I’m not sure if something is wrong with my baby. She’s 3 weeks old. Tonight she’s acting different, she’s crying her lungs out so I rock her in my arms & as soon as I lay her down like 2 minutes later she starts crying her lungs out. She’s also eating before 30 minutes but she eats so little where she’s not even latched that long where I can tell she’s full. Not sure if her tummy or something are hurting...
