I have a very very early memory that my Dad disputes about having a line of shrubs in the garden, I've not seen a photo of them there but I know they existed, Dad says I can't remember them as I was too young when they were removed. But he doesn't dispute that they were there!
The next datable memory was when one of my siblings was born, and I remember all the adults cooing and ignoring the two older children, so I'd be 3 years and 3 months then, and again when the next sibling was born, waiting on the steps to be allowed to go into see the new baby so just over 4 then.
