DS (8) is my PITA child. Eg: very angry shouting, aggressive & bad-tempered first thing in the morning, or any time he's hungry. Feeding usually sorts him out; personality may well flip to cuddley & smiley after feeding. I strongly suspect he's mild ADHD (hyper-impulse type).
I have 3 other children who are not consistent horrors when hungry, especially in morning.
Googling suggests that serotonin levels may be issue with his anger-aggression, talk of using L-tryptophan supplements for adults with Aggression-Hostility-Anger syndrome, or as a general help for children with ADHD.
Talk of dangers of L-trytophan supplements, but that seems to be down to contamination from a specific supplier, & high dosages, back in 1989.
I don't want to try anything too clever with biochemistry, I was just thinking about giving a small dose (220mg), each evening, over 3 months. See if it helps with morning mood, anyway.
I have looked at other options: fish oil or general diet changes, either tried or doesn't seem right way forward.
Anyone given L-tryptophan supplements to their child? Any thoughts?
