Dear parents,     According to me up to 5month give exclusively breast feeding .if baby is gaining weight your milk is adequate. Only baby weight is criteria. No body can say it is less or more as not measurable. Baby gain in weight ,playful and active. Mothers milk is adequate. As milk goes in stomach it comes in contact with Acid HCL&is converted to curd, if baby regurgitate instant ,milk in same form comes, After some time curd in flakes seen &after sometimes solid curd would regurgitate.
