Need some advice...my 16 month old lately has been pooping on the floor in the morning so bad that I have to hose him off in the shower. (the showerhead pulls down) And around his peepee is really red....like around the head. he hasn't been wanting to drink his milk like normal because he there up from drinking it last week, so he's been wanting juice. mind you I water down the juice every time. he also will choose just drinking juice over eating. could these issues be related and what can I do to help?
