i just posted a message and wanted to add a little to it...when i said she has screaming fits i mean she arches her back her eyes go blank and she screams at the top of her lungs. she picks things up and throws them she will hit, kick, punch, pinch, and call you names its like anything she can do to hurt you. One day at daycare she was in a bad mood and a little boy walked by her and accidentally bumped her and she punched him in the face and when they tried to put her in timeout she decided to pull the phone jack out of the wall. This is the 2nd daycare she has been in since being put on singulair the first one she broke 3 of the owners fingernails off by kicking her and she got suspended for a week due to her being violent towards other kids. As far as the asthma goes I will say that singulair works great for it i haven't had to do as many breathing treatments on her but i will do 50 breathing treatments a day if i have to because she has been off of the meds now for 2 weeks and i am seeing a slight improvement in her attitude.
