My 14 month old is tiny - he is 17lb (just) and approx 70cm. He has a hole in the heart, eats very very well, drinks his milk, and is developing normally apart from his size and lack of teeth! He wasn't premature but was 6lb 1oz when he was born. The doctors have done numberous tests to try and find out why he is so tiny but we are hitting a brick wall. Is anybody else in a similar situation? Thanks
