My 2-year-old eats like a sparrow. Rare that she would eat three proper meals per day. Then she seems to make up for it every few days and have a pig out. But she doesn't use up much energy, she potters about and tinkers with things.

She's tall but skinny. I could worry about it but really, it runs in the family so it's in her genes.

Glad that you've worked out what works for him though. Sounds like you're on to something!
