Hi dr. My name is ainsley from south africa. I have a 6 month old baby girl who I have started introducing solids to. At the moment she just eats porridge and her formula. She is on NAN 2 now which I have started her on from six months and she seems to be constipated. Her poo is very hard and painful for her to pass, she cries everytime. I have also noticed because of the pressing she has developed a tear by her bum. I have used lacson once to help soften her poo but I am scared to give it too much. Should I change her formula?
