scheduled feeding?

Brittney

So my little boy is a few ounces underweight so his pediatrician told me to supplement formula and feed him every 2-3 hours. hes 3 months old and ive been trying but even if i give him formula he just gets so hungry before the 2 hours unless i give him like 8 ounces of formula. im thinking ill keep with the supplementing but not sure if i should keep with the 2 hour thing. any suggestions or advice?
