<s>[INST] My 2 year old woke up very sluggish and lethargic today. I usually have trouble making him sit down, now it s a struggle to keep him up. He is dead weight when I pick him up and he s just not normal at all today. I dont know what the problem could be! Please help. [/INST] Hypoglycemia some time may cause this type of symptoms. So go for Rbs.  And give proper feed. If hypoglycemia is there go for proper investigation. </s>
