My 22 month old son recently saw a second neurologist and although he did not diagnose him with ADHD or ADD he definately agreed he is hyperactive! My main concerns were his aggresiveness, sleeplessness, hyperactivity, and mild developmental delays in language/others. One of my main concerns was the lack of sleep my son falls asleep really late usually after 11pm and then wakes up every two hours on the good days~on the bad days every hour. So the neurologist recommended we give my son up to 3mg of melatonin, I started on Tuesday and it has worked miracles!! My son falls asleep about 10-15 min after taking the pill and only wakes up twice the whole night!!! My question is does this dose seem too high for his age the doc told me it was fine to give him up to 3mg. Overall he seems happier and less cranky in the morning!!!
