My 14 month old DS has always been a 'good eater' but in the last month or so he seems to have developed an insatiable appetite. I try to make sure that everything I give him is filling and nutritious but when he has finished he cries for more - he has 'filled out' a wee bit and has just started walking in the last couple of days. I am worried about him putting on too much weight because DH and I are both overweight and always have been DS1 who is 2.5 probably eats less than DS2. Any suggestions?
