The food Standard Agency published a report in May 2009 saying that children between 1 and 4.5 years old should not have rice drink as a replacement for cows' milk or infant formula. I would recommend that you try your child with a calcium enriched oat milk. Also do make sure it does not say organic...

I would recommend that if you do not wanty your child to use an infant soya formula then I would suggest you try your child with Alpro soya 1+.
This milk is fortified with iron and vitamins aswell as calcium.
