My 2 year old Daughter has all of a sudden wanted to just constantly lay in the bed and watch tv...?

She is normally a very active little girl and shes still active when she isnt wanting to lay down in the bed and watch TV...She has been sick with bronchitis for a week, but she is almost over it. She no longer has a fever, but she has a small cough. This really just started when she got sick, but once again, she is almost over the sickness and this is still going on. Everytime we go upstairs she will say MY BLANKIE, BED, TV!!!! And thats all she wants to do the makority of the day...she will SCREAM bloody murder if I dont let her...Is this normal or anything to be concerned about???
