Help!!! Pl recommend dietician for kids

Hi everybody

My kids are going to undergo a sea change in their lifestyle very soon as they are moving to a school quite far from my house.

My little one who is 3 and a half years old is is going to be in a creche for a couple of hours after school. I would be packing her food.....I am very keen to know if there are pediatric dietitians I can consult to ensure I pack a wholesome fare for her and the elder one - 6 and half year old......I am suddenly feeling unsure of what to pack daily.

Regards
Radha
