Congratulations Sunshine!
L can be very violent too, pinching and attempting to gouge out my eyes
She finds it funny when I tell her off, so I've taken to holding her hands for a few seconds whilst doing saying no. She hates being constrained, so it's a deterrent, but it doesn't actually hurt her. No idea if it's the right thing to do.
She is sleeping as bad as ever. Last night I got 3 hours. Tonight it's DH's turn :) She runs everywhere but isn't really talking, although she did say 'Uh oh' today, which is what I say every time she falls over. She decides whether or not it hurts based on my reaction, if I gasp she cries, if I say 'Uh Oh!' she's fine.
Hope everyone gets lots of sleep tonight!
