baby development/ childcare

Hey guys! I'm qualified as a level 3 in childcare and I've just been offered a role as a key worker. For anyone who doesn't know, this means I'll have specific children who's files I need to write and keep up to date with their development etc. 
Im really looking forward to creating files for my children and I want to make them as awesome as I possibly can. So, I need some suggestions from you guys! 
Obviously there's certain things I need to write in these files but because they're mine I can make them my own so I can create my own layout or my own styles or my own way of doing things. 
So anyone who has some suggestions to what I could put in these files please comment. Wether you have children in nursery and you want to share something out of your child's file or if you have children and you'd love to know something specific about your child if they were in nursery or if you're qualified in childcare and you want to share your ideas etc etc. Please comment!
