Help my 5 month old appetite has gone crazy...?

yes a babies appetite changes as her body grows, she will begin to slow down when the growing stages stops. dont worry about how much she is eating as long as she is a projectile puker u are fine. she will gain weight and grow out of her clothes but she will trim down once she becomes increasingly mobile. just feed her and keep her happy and if her teeth were bothering her she would slow down the eating i promise. u may want to change her formula to carnation formula and see if that keeps her fuller longer. god bless u and your new baby and enjoy her she is fine...
