DD (11 months) just fell backwards from standing, I'm not sure quite what happened but she seemed to forget she was standing and just fell straight back after a tiny wobble. her head made a huge bang at the back and she screamed and was breathing panicky for about a minute (will usually calm down after a few seconds if she bumps) then bf and calmed down.
Do I need to get her checked as it was quite a hard bump or should I just keep a close eye?
