A little off topic but in relation to the how quickly things can happen - when DD was young, about 2 yo from memory we were staying at a resort that had an indoor pool. We all hopped out of the pool & both DH & I turned our back on the pool to grab our towels to dry ourselves. When I turned back, I couldn't see our DD - there she was in the pool, under the water looking up at us. :-/ Scariest thing ever & we didn't even hear her fall in.....
