DS was EBF until 6 months and did 1-2 dirty nappies a day. He's now 7.5 months and loves his food, is gaining weight well (moving up the centiles) and very active and alert. BUT for the past couple of weeks, basically since he's been eating proper amounts of food, he now does at least 5-6 dirty nappies a day and his poor bum is getting sore from cleaning all the poo. Is this normal? Please tell me it will pass soon!
