My 16 month old little girl, who has up to now, and is still in general a very loving and gentle baby, has started to lash out at my neck and face. I say 'no', or 'stop it' but she appears to think this is funny and does it again straught away. She drew blood the other day and it is beginning to get very upsetting. I have tried putting her down staight away when she does it but then she gets very upset and starts to ball her eyes out. I am not sure if she understands why I get cross. I don't know what to do - is this normal behaviour - part of a phase?! Please help!
