bedtime laughter

Tonight when i put Abbie to bed we were reading a story and i was having her point out all of the animals on the page. At first she would point to the right animal, but eventually she started pointing to the wrong animals and i would say "no, silly - that's a (insert correct animal here)" and she would start laughing hysterically (which in turn made me laugh hard) - we did this over and over until our stomachs hurt from laughter. She is such a doll - i LOVE when she sincerely and genuinely laughs at something - i think it's precious. I hope her laugh always stays the same, it's one of my favorite things about her!
