Welcome to the TDC.
I have a 3 year old grandson. When he use to visit all I ever did was sit in a big chair. Just too tired to get up and I sure could not bend down to play with him. He use to cry when ever he came over cause he did not want to be here. Now with 90 lbs gone I have so much energy and I can get on the floor with him, run and take him to the park. He just loves his new grandpa and ask to come over here all the time.
I'm sure your little girl will love the new you to. Just take it one day at a time. Your going to get so much more out of this WOL than just smaller pants.
