Hey girls, it's been a long time since I have posted but I need some serious advice. Ava is going on 15 months old and she has been hitting, pulling hair, and screaming for a while and as of recently has begun biting me (only happened maybe 5 times thus far). She bit my hand when I was changing her diaper, bit my neck after she pulled my hair, and bit my leg a few times. I have tried ignoring her, firmly but calmly telling her "NO", I have tried whispering to her and asking her to be nice, I have shown her nice, etc. The only two responses I get out of her no matter what tactic I try is her laughing hysterically and attacking me again. I feel like I have lost complete control of her and I end up giving into whatever she wanted that caused her to behave the way she does. Sometimes when she laughs hysterically at me I can't help but laugh to...even though I know it's horrible but she is so cute sometimes. ARGH! Sometimes she hits, screams, pulls hair, and bites for no reason at all. There have been several accounts where I have been playing with her on the floor and talking to her and she came out of nowhere and pulled my hair or hit me in the face. I DO NOT HIT HER so where she is getting this type of behavior I do not understand... Is this normal for her age? Possibly a phase in a toddlers life? Any advice or tidbits would be greatly appreciated! Thanks!!
