First of all i want to know the weight and height of your child if these are above 3rd
centile there is nothing to worry.
Weight should be between12to18 kg at 3.5 years.
Height should be between 88 to 103 cms at 3.5 years.
At this age it is normal for children to be fuzzy about eating you have to work hard to make
8to 10 episodes of upper tract infections of short duration per year are also normal for this
I think these suggestions will decrease your anxiety
Wishing good health for your child.
