My dd1 is was always the smallest in his class He's 20 now and a towering 6 footer!!!
NM I fell down down 3 steps on the ice in Dec, I was holding dd and ds2. It was horrendous,I just let go of ds2
and fell in an almost upright postion to keep dd safe. It was weird, it went so slow and I didn't mean to drop ds2 but instictively know what to do to "save" the baby.
I hobbled over to my friend's house and then creid for about half an hour. I got a tremdous shock. Should have seen my ankle the next day EEEk.
DS2 was none the worse for the fall, at that age the tend to bounce 
I remeber my mum teling me, when I was wee, my mum had a pram,with a sort of toddler seat on it. She left us, while she went into the shops and I rocked and rocked, so I tipped over the pram. She rushed out the shop ignoring screaming toddler (me) and scooped the baby up. Another customer saw to me. SHe said she couldn't help it, number priority was the baby.
I understood completely after I had that fall.
