I got into a discussion regarding difficult child with a couple of people who respect what is going on with us but they asked how old she was when I knew something was 'different.' When I said I could tell something was off as early as 1-2 months old they were shocked. I explained how difficult child couldn't handle the smallest change in routine, the sleep problems, different moods than other babies etc and one of the two asked how common it was for parents of difficult children to notice these things early on. My answer was "I dunno, but I know where I can find out!" Now Im wondering if I'm odd for noticing so young lol. So how old was your difficult child when you knew something was off and what is your difficult child diagnosed with?
