She might be going through a growth spurt. Feed her in small increments so you don't over feed her.

she suckle and move her head around fuss all the sighs

@mrs.mahsill, my son went through bouts like that where it felt like he was nursing around the clock. When he was doing that, he was going through a growth spurt.

read the book "on becoming babywise" it's very helpful on feeding and sleeping information. you said she wants to eat every 30 minutes is she rooting for food or is she just crying every 30 minutes?

if it's before that time frame then they just want to suck on something. if you think they are hungry every hour because that's when they cry you are turning then into a snacker they eat for a few minutes and then stop if they do that they don't get to the rich hind milk that helps them grow

she Wanna eat every 30mins

every 2 1/2 to 3 hours
