Little baby - any reason to worry?

Jodi, I wouldn't worry that she only drinks 4 ozs. at a time. My four year old never did drink 8 ozs. of formula. She is in the high end of the average for her height and middle range for her weight. Her pediatrician wasn't concerned and neither was I, because she ate when she was hungry. She was not on a set schedule for feedings but she would eat every 2-3 hours. I have a granddaughter is 1 1/2 years older than my 3 1/2 year old. When my 3 1/2 year old was a year old she was as big as my granddaughter who was 2 1/2 at that time. They are now the same size. Yes, she is big for her age and my granddaughter is small for her age. But developmentally my granddaughter was walking by herself at 9 1/2 months(she looked so funny being so small and walking) and pottie trained by the time she was a year and a half. Then again she has an older sibling. It's funny now days pediatricians don't start babies on solid food until they are 6 months old. When I had my first child 33 years ago they were started on cereal by 6-8 weeks on fruit by 3 months, veggies at 6 months, meats at 9 months and by the time they received their measle vaccine they had to be introduced to eggs to be sure they didn't have an allergy to eggs because the vaccine was grown in eggs. It sure was an eye opener when I had my last child at 45. Needless to say I never waited till my children were a 6 months to start them on solid foods, I started my 3 1/2 year old when she was 3 months, I felt she wasn't getting enough just with formula alone because she wasn't drinking but 3-4 ozs. By the way none of my children have any type of allergies or digestive problems. I think that was the reasoning for waiting till a child was at least 6 months before introducing solid foods. Just as long as she is growing gaining weight,don't worry. If there was a problem I am sure your pediatrician would have alerted you. For her height she weighs what she should. She is just petite like my granddaughter.
