Just googled it and can't find any info on whether it's ok or not.
Just bathed DD3 and her BCG which had started to crust over a bit (normal I know) had a bit of a head on it. Was washing her when I noticed pale green 'stuff' oozing out of it and down her arm. There was quite a lot of it. I gently washed it away and it was soon replaced with more.
I've left it, not no oozing, and dressed her and am not overly concerned but don't remember her sisters doing this.
Is it all totally expected and normal?
