Today my baby girl turned 6 years old...and she has her first loose tooth! She is so excited. What i think is crazy is that all her life she has seemed to hit significant milestones right on her birthday. Literally the day before her 2nd birthday she decided (on her own) that it was time for her to use the potty. Other years it she just seemed to mature in noticeable ways right around that time as well. Have any other mom's noticed any big differences on or near birthdays??
