I have been surfing the wave of hormonal tween for the past 4 maybe 5 months. I don't remember it starting this early with Olivia but then again Hannah seemed to do everything faster than Olivia did for the pure and simple fact that when you have two children the younger one tends to want to do EVERYTHING that the older one is doing and not wait until the same age bracket to do it in.
Case in point. Hannah started walking at the lovely age of 9 1/2 months. Olivia was closer to 14 months. Hannah potty trained over a few months and was peeing like a champ on the potty by age 2. Olivia held out for reinforcements (ie: my mother who had to travel from Florida to Ohio) in order to coax that tushy out of a pull-up and into Big Girl panties. This was accomplished after she was 2 yrs old. Olivia breastfed until 18 months, Hannah dropped that and the bottle by 9 months and demanded a sippy cup.
So while Jon and I steeled ourselves for the fact that "it" meaning puberty was coming, we had NOT in any way shape or form prepared ourselves for the fact that striking double digits on the birthday cake would bring about a tidal surge of dramatic outburst, raging mood swings and the onset of what appears to be a reflux disorder.
