autumn's 25 months old

Can somebody help me out? At what age do you stop referring to your children's age in months? It sounds so unnatural to say she's 25 months old but 2 years old doesn't feel quite right either. Can she really be 2 already? 2 and a month no less.

Here is a picture of her suckering gammy into reading her a story.

Here is a picture of her saying "seriously mom? another picture?"

Here is a picture of her cheesy face

Here is one of Charlee showing of her gummy smile
