I have heard that it is quite typical for toddlers to get the majority of their nutrition for the day by lunchtime - it's not at all unusual for them to not want to eat at dinner.

Liam has always been a big eater, so this isn't a challenge we've had. Quite the contrary - with Eric and I both being overweight, I worry that he eats too much, or too much of the wrong foods.

Trust your mama instincts - if you're worried that something is wrong, definitely get it checked out. (I have more than once known Liam had an ear infection about 1 day before the doctor could actually see it.)
