I AM A LITTLE SAD TODAY!!
While mine are still younger than your baby I can relate I cried like a baby when I had to buy my baby girl her first bra for school this year. But I have to agree with HappyCat what a great mom you are to have one in todays society that has a job that quickly after getting old enoough. Congrats on raising a good kid!
OK I felt like that when my daughter turned 10, 13, 15, 16, 18, 21.... but she is 23 I still feel that way. of course she is married and has a 8 month old and i still feel that way... and even more so with my grandson. It gets better I do promise and things change but that feeling will always be there...forever..
