HELP! I've got a kid that keeps getting sick....He's had everything you can think of. Now, he is "a bit weak". Nothing...and I mean NOTHING is working. I've given him medicine that just makes him more tired. I've tried just putting him to bed. That's his only symptom...a bit weak. I even wasted money on a doctor's consultation that said he was fine. He's NOT fine. Can anyone help me please? Thanks!
