Yup, that's right I have a biter. Bailey has taken to using her sister as a chew toy. We're not talking little nibbles here and there. No, I mean full on breaking the skin, leaving big bruises biting. And all over. She has one on her face, one on her back and one on her arm. Poor Reagan is starting to look a little bit like a vampire victim. We've tried showing Bailey the mark and telling her how sad sister is and how it hurts, but I think she's too little to understand. What do you recommend?
IUI # 1 on 1/19, Beta 2/1 = BFN, Hysteroscopy on 2/15= 5 polyps removed, and cervix cleared, IUI #2 on 4/15 = BFP, Beta#1 on 4/30 @ 15 dpiui= 279, Beta #2 on 5/9
@24dpiui = 10,154, U/S on 8/5 = TWO GIRLS! Born 10/16 at 28 weeks.

Re: Help please! RE: biting
First you need to figure out what is causing the biting. Does she bite because she wants a toy or is mad? Or is it that she is hungry? Or does she do it to vent happiness (yes this actually can be a reason)? Then when the situation the precipitates the biting happens intervene and give her something else.
Example: I bit as a child because I was over sitmulated and didn't know what to do with all my excitement. So when my mom would see this happening she would take me into a dim room and hold me tight, making sure not to get bit herself.
Example 2: Riley bites when he wants to nurse. I have taught him a sing for milk and now as soon as he signs milk we nurse.
Stopping biting is hard, it is a lot of work but with time and effort kids do grow out of it. Good luck and I hope my advice helps.
If you do the holding her just be sure not to get bit yourself. Also as she gets older you can give her the words to say how she feels. My nephew bit from getting mad and my sister handled it great. She removed him from the situation and got down on his level. Told him she knew he was mad, but that biting wasn't okay. But that it was okay to hit the pillow on his bed (he was 2.5 when he started biting). Then they would go hit the pillow together. When he was done she would praise the holy hell out of him. Later when he learned to tell us "I mad! PILLOW" and we would run and get the pillow. But he did stop biting his little sister.
ETA: Biting at an early age (before 2) is much more common in twins and multiples. So please don't feel like you are the only one going through this.
Thank you so much for the advice! I really appreciate it! And I was worried that she was biting at such a young age, so I feel better now.
