Oh that made me laugh!! Ithought it was just me!!
This time it's been fairly clean, but last time when it popped 'out' I did notice lots of fluff and what looked like a scab or something? Not sure what it was but I eventually picked it all off! (vom emoticon)
This time my belly button is apparantly a doorbell - DS2 keeps pressing it and saying 'ding dong, come out and play baby'.
