You know when toddlers get a huge bang on the head (but they're asleep at the time) and people say to 'keep an eye on them' .. are you supposed to try to wake them up? and how awake are you supposed to try to get them?
(DD's buggy fell backwards with a big thump because of weight of veg etc ... she was sleeping and the back was flat back .. of course now she won't wake up properly and I don't know if I'm supposed to be trying to wake her up properly or just let her sleep because she's sleeping anyway)
