I absolutely LOVE big/lil week! We do it the same way here with the C-H-I-O. I loved getting gifts when I was getting my big sis, but I almost love getting a little even more--it is so EXCITING!
I got my second little this semester and I swear she is just the sweetest thing! During big/lil week, before she knew I was her big sister, she called to wish me a happy 2 and a half year anniversary with my fiance'--it was the cutest thing ever
I adore my first little sister too though--she is such a gem! We're having a hard time finding a good spot in our schedules for a family outing, but it's sure to be a blast!
I hope this all goes to show that we older gals are just as excited about new members joining as the nm's are!! I'm super glad your time with Chi O is only getting better and I wish you many more happy memories as you get to know your sisters!
LiCO,
April
