DS had his fourth birthday this month, and he wanted to get a frosted cookie. After he ate it, he was terrified of the balloons we had blown up for him, terrified of sticks and terrified of the strings on his bedding. We have not seen these fears in months. After about an hour, he was playing with the balloons again. I was thinking that maybe all the sugar he had (we don't normally give him much sugar, if any) made it harder for him to calm his fears.
Has anyone else had an experience like this?
