I encountered this with scrapping my oldest who is almost 17. I am way behind on his photos. He was born in 2004 and I am almost done with 2005 but when I got to his 11 month photos that I took. I don't remember what his milestones were at that time. I took notes up to about 7 months and stopped. I went back to a few older photos to get a sense of what he was doing at that age but kept it pretty vague.
