Hi everyone,
My baby girl is nearly 4 months old and has been EBF since birth. In the last few weeks we have started introducing a small amount of formula before bed just to try it out (about 2/3oz).
Her poos have always been a mustard colour and fairly runny but since introducing the formula they’re like an army green colour and much thicker like peanut butter 
does anyone know if this is normal? I’m not sure if it can be down to the formula or not. She seems fine in herself. Possibly abit more wingy but I’m putting that down to teething as she has red cheeks and can’t stop chewing everything!
Any advice would be great
