Hello Jacob, my son. If you wanted to know what you were like when you were less than 6 months old, I can tell you.
You are very much like most babies. You cry when you are hungry or uncomfortable. You can't walk or talk or sit up unassisted. You are trying very hard to talk. Perhaps when you are a bit older you will talk a lot.
We play nursery rhymes on TV and you like some and dislike others. You dislike "Head, shoulders knees and toes". You like Bingo the dog. You also like some Spanish ones with dancing chickens. You also like the finger song. "One little finger, one little finger, one little finger, tap tap tap". You already have a very distinct personality and you are only 3 months old.
I wonder every day what you will be like when you are older and what the 20s decade will be like for you, something you know better than me since you have been there already.
