Hi, dd2 is just over 4 months old and exclusively breast fed. I notice lately that she has quite a lot of mucus in some of her dirty nappies. Also her poo is mustard in colour (like I remember from dd1) but very liquid and not a grainy texture. Is this normal or would you get it checked. She is very healthy and happy and weighs around 14lbs now, she was 7lb 15oz at birth. She is teething though and has recently cut two teeth. Could this be a cause? Thanks
