For the first 8 months, I breastfed my son exclusively. Due to some problems with low milk supply, mastitis, and a lot of frustration/stress, we went to the bottle - 100% formula. We've been established with that for a month now, although he will only take between 13-18 oz in a 24 hr period. He's always been a "snacker", taking in small amounts each time, even if we wait 4-6 hours in between. He doesn't, and never has taken, puree or anything else from a spoon. He likes to feed himself finger foods, and he does pretty well (avocados, cheese, pasta, crackers, fruits, soft veggies, etc). He doesn't eat a ton, but he does ok and then he lets us know when he's done (throws it around or starts to fuss to get out of the chair). He is now 21 lbs and his weight gain has been normal. So my question is - is he getting enough nutrition with taking in such small amounts of formula? At meals, in the high chair, I give him water and sometimes a bit of juice, which he drinks out of those 1 oz medicine cups - he does much better with those than a sippy cup. Even so, his total juice/water is maybe 4-5 oz a day. Should I be doing something different? I mean, it's not like I can make him drink more formula...and even on days when his solid food intake is very low, he doesn't make up for it with the formula. I guess I just need opinions and to hear what other babies his age are doing.
