Hi there!
I have just this to advise: Kids will never go hungry. My sister lived off soda crackers. She's 42 and still petite, but she just didn't need to eat that much, she still just eats here and there.
I know you're concerned becasue she's only a baby. But my mom always told me this, " J., if your baby is loved, hugged, fed and changed," that's all they need.
Kids grow in sperts. They grow up and then out, up and then out.
Your child will let you know when she's hungry.
She'll let you know.
Don't worry, unless she starts to lose her energy. Then I would be concerned. But if she's having fun. Why worry!
J.
