I do a journal for children under two. Once they turn two no longer need it. I find it is helpful for the parents to know what they did and ate throughout the day. I find the meal description important bc if a rash or something appears than it may be a food allergy, especially at young ages. At these young ages the kids cant explain to parents what they did or ate. Once they are talking and being more independent i get rid of the journal. Its also easier to recall things when the parents start asking questions lol. Sometimes the days are soo hectic that you cant remember it all.
