C.M.
sound just like my 4 month old. She is breastfed but often takes bottles too - she has to tag along to a lot of her sisters' events and it's just easier for me to give her breastmilk in the bottle.
She eats around 7am, 11am, 3pm, 7pm and a little more at 830pm, then down to bed at 845 and sleeps until 7am. When from a bottle she takes about 6oz. I have not yet started cereal. She's been in this routine since 2 months old and my older two were the same way. She does not fuss or act hungry in between feedings, and my pediatrictian says she is growing and developing right on track.
