Hi, can anyone help. I'm a new mum to 7 week old who is constipated. We started on sma then moved to Aptimal, but he only has a pooh every 3 days and its very little and hard'ish. We gave him lactulose following the doctors advice, and then he is able to go for a day or 2, then constipated again. Any advice would be greatly appreciated. My little one is suffering
