My daughter is 5 months old. Can she aleady be tantruming? Since yesterday, she's been doing this thing like she's going to throw up. She did it yesterday because she was all hyped up and didn't want to go to sleep...then she would scream really loudly. I thought maybe cause she was hot because I swaddled her in her receiving blanket, so I took her out of it and continued to bounce her. She kept doing it. It scares me a little because I don't want her to actually throw up. It's like she's making herself do it. Well we were up till 10:30, she tired herself out, then she went to sleep. She continued to do it today....not going to sleep but other things. She was sitting on my lap while I'm here on my computer typing or looking at stuff and she does it. She did it while she was on her swing. She had a toy in her hand...she did it in her excersaucer. Maybe it's just a new way of gettin my attention but I don't like it like WTH! What do I do. I don't want her to do that. SHould I ignore it what??
