Mommy, I cant...

"Mommy I CANT, Mommy I cant!"   These were the words out of my 3 year olds mouth today.  She wanted me to help dress her doll.  I told her to try it herself since she is a big girl. Then she said something that got me thinking.  She said, "no mommy, I cant do it because you can do it."  Is she not wanting to try things on her own because she knows I can?  Is she being lazy?  I know it is a typical toddler remark, but I want her to be more independent and not ever think she cant do things.  Her daddy is a great example of a can do attitude.  My hubby knows he can do anything with the right preparation.  I want her to get that down!  TRY TRY AGAIN my sweet lil girl!  You can do it!
