My little one has been on Aptamil Pepti for just over 2 weeks now after finding out he has a potential cows milk protein allergy.

He has definitely been more settled since changing over to this milk. However, the last couple days he has been popping lots more than usual. Perhaps 4 nappy’s a day. Just changed him this evening and I noticed tiny red speckles in his poo. Does this seem normal? Or should I contact paediatrician in the morning? Thank you, any advice appreciated
