My son is only going on 10 months, but when I look back on my own childhood it's not the planned activities that stand out. It's:
My Dad chasing us around huge bushes, pretending to be a monster, in the freezing cold.
Having buckets of cold water chucked on us in the summer, and squealing at them to do it again.
Singing old songs on the long walk home after a day in the park.
Fish and chips/Sayer's cheese and onion pasties while Christmas shopping.
Being taught about different plants by my gardener Dad.
The smell of homemade vegetable soup of a cold winter morning. Dad would make it early so we could tuck in when we got home from a day out hiking.
Reading Lord of the Rings, Harry Potter, and His Dark Materials together.
...see what I mean? I could literally go on all day. And these memories go way into adulthood, too, they're just a little different. Don't worry.
