What do I write in a birthday letter to my child?

One specific memory, one thing they taught you, one hope. The prompt builds it from a few details rather than generic sentiment.

Can I catch up a baby book years later?

Yes — the prompt asks the memory-jogging questions in order so you can fill gaps from photos and dates.
