Rylee and her Jammies

Let me start by saying that over the last two or three months Rylee has been going through a phase where she will not where anything but "comfy" pants.  This included anything that does not have a button or a zipper.  They have to be slip on type pants, preferably  sweats!  This began back in early october or November.  In December, she started to ask to wear her jammies as soon as it got dark.  This was about 4:30 or 5 in the evening...not too bad.  Then after a few weeks of that, I'd get her dressed in the morning and then by lunch time she was asking to wear her jammies.  Now it is to the point where every morning, instead of getting dressed like normal children, she gets dressed in a clean pair of jammies.  Is this weird or what?  Now, she is probably like me when it comes to this.  I prefer my jammies/sweats too.  But I have never heard of a three year old wanting (or caring) about wearing "comfy" clothes.  The good thing is, I can usually change her into non-jammy comfy clothes if we are going somewhere, although sometimes she puts up a huge fit.  I've decided to just let her wear her jammies most of the time because at this point, I'd rather pick my battles with my very stubborn three year old!  Call me crazy....
