Doing something right?

So sometimes my kids are handfuls and can be difficult.  Little Miss #3 and her 2 year old independence had been rough. But then there are moments that make you feel like maybe you are doing something right. She came up to get diapers and wipes so dad could change her. I helped her since we had to put them up high (she has decided to help herself to her own diaper changes....fear and tremble.) But as I handed them to her she turned back at me and said s cute little "thank you" that made me we might be doing okay.
