Any Suggestions???

I am not one of those lucky women that don't have to deal with morning sickness and sail right through the first 3 months. No, no- I am one of those women who have "all day sickness" instead of "morning sickness" so I am really taken down for a while when I get pregnant. I have moved past all of that but I am afraid a residue remains that I am not quite sure how to fix. Tylie had to learn that I was sick for that time and was not able to play with her like I normally did. I tried to explian to her that the "baby" was trying to grow and it was making mommy sick. Well, this backfired on me in a way that I would have never imagined. The other day, I got home from work and was laying on the couch for a minute before I got up to make dinner. Tylie walked over and said "mommy, what doing?". I told her that I just needed to take a rest for minute. Then she proceeded to lift up my shirt, get a mean look on her face, and said "Baby naughty, I pinch baby." She attacked my stomach and kept repeating that she needed to pinch the baby. Now whenever I lay down for a minute she thinks that the baby is making me sick and she needs to get mad at the baby. She has gone so far now and biting my stomach and telling me "I bite baby!" Now, at first this is funny but I am worried that she is going to have a mean attitude with the baby when the baby is born. Jake's sister recently had a baby and Tylie was over visiting them the other day. Jake said that she loves to hold the baby and is really cute with him. I hope this is how she will be but I can't help but be nervous. Any suggestions??? How do I fix this?
