My DS is nearly 3, and I have a DD who is 3 1/2 years older. I was looking through old photos of my DD last night, and came across some photos from a holiday when she was exactly the age my DS is now. It absolutely blew my mind that she was the same age, from my memories she was much older than he is now on that holiday. I thought of her as so grown up then compared to the tiny little baby she'd been, whereas I still think of him being a very baby-ish. I think partly it's an oldest Vs youngest thing, and partly because she talked very early and at this point her talking was very grown up for her age, whereas his language is OK but he still talks very much like a toddler.
I feel a bit guilty looking back, I think my expectations about her were probably too high as she seemed so grown up. Or maybe I baby him too much. Anyone else feel like this? It's making me think a lot about my parenting, and how much it is influenced by my perceptions at different points in time.
