Have noticed a few times this smell on my DS [2.6yrs] He has never drunk tea or eaten pear drops but the smell is very noticable. I vaguely remember it being an indication of something but dont remember what.
He does not eat much at all but is always thirsty. Drinks a lot of milk and water [about 4 ints altogether in 24 hrs}He goes from a bouncing ball of energy to lethargic but I put that down to a lack of food to sustain energy.
