No NO NO NO!

I noticed that my youngest baby keep on saying No lately. I was like, what is going on?, wondering why she keep on saying  on. Then I realized that my eldest also used to keep on saying No before when she's about her age also. My Sophia is about 20 months old now. My only regret is that I didn't get the chance to update their baby book., I could have compare the dfference. I feel so unfair because I did my eldest and just didn't finish Eric and Sophia's. I'm just hoping that I will be able to finish it this month.
