DD is just over 9 months and has started biting me about 3 weeks ago. She smiles and thinks its funny. I've tried shouting, put her on the floor, stop feeding and put her to bed but she keeps doing it. What do I do??? I don't want to stop feeding. She normally feeds really well in the morning just midday and evening. I'm cutting down to 2 feeds- morning and evening now to see if that helps.
