I know it looks like a dumb question but I'm really wondering what to do here. DS has NEVER eaten like "normal" in the past. Since birth he's always eaten like a bird. There have even been days where he didn't eat anything but a handful of dry cereal all day because he wasn't hungry. Lately(within the last week) he's acting like he's dying of starvation. The day before yesterday he ate:
2 bowls of Kix cereal with a banana chopped up in it, a handful of blueberries & 5 strawberries for breakfast.
Then a package of instant oatmeal
2 graham crackers and a small dish of applesauce
A whole PB&J sandwich with pretzel sticks for lunch
Then 4 fish sticks and some baby carrots because he wanted another lunch
4 more strawberries, the rest of the blueberries and some grapes
A few Ritz crackers and some pieces of raw green pepper with Italian dressing to dip
Then some celery with peanut butter and a tiny box of raisins
Then dinner was french toast so he ate 2 pieces of that with some syrup to dip, a couple pieces of bacon, and a scrambled egg
He had 3 16oz bottles of water, 3 kid cups of juice(50% 100% fruit juice and 50% water), and he had 4 kid sized cups of Lactaid to drink.
Yesterday he ate his noraml 4 meals a day and today he's back to eating like he did the day before. Everything all day long. Could this be a growth spurt?
He normally eats breakfast, lunch, dinner, snack(sometimes). Should I start giving him snacks between all meals? I don't want him to not eat because he's underweight and honestly needs to gain weight so as long as it's healthy food his pediatrician said to never deny him anything if he's hungry because he will go for a whole day willingly not eating much all day. But at the same time I don't want him to be eating all day every day and eating whatever he wants. I did not call the pediatrician about this yet because DS goes for his 4yr old check up in about a week but that's what he's said about feeding DS before when I've asked.
So, how do I feed him? Breakfast, snack, lunch, snack, dinner, snack? What's "normal" for a typical 4yr old?
