Some parents think their child (of any age) is eating too much food, and others think that their child is not eating enough food. How do you really know??
Too much?? If you have been restricting the amount of food that your child is allowed to eat at scheduled meals and snack times, it IS possible that they have reacted by overeating when they get the chance. If your child knows that they will not be allowed to eat until they are satisfied, they will compensate by stuffing themselves when they can. However, if you have allowed your child multiple portions if they are still hungry, and not tried to control the amount of food they eat, then they probably really are still hungry!
Children are the best regulators of their own appetite. We know some days (or weeks) they eat next to nothing and you wonder how they survive. Other days they could eat and eat and eat! This depends a lot on their growth rates, teething, illness, etc.
Remember the “Feeding Relationship” rules. The only role of the child is to determine how much or if they eat what they are offered.
If you are worried because your child is “overweight”, try not to be worried. People come in all shapes, and weight is not always the best indicator of health. If you offer your child mostly healthy foods at regular times, in the portions they choose, they will get the food and nutrition they need to grow to their healthy weight (which will change as they age and grow).
