Maybe it's just another aspect of toddlerdom or maybe it's because she's still labouring under a super-cold, but The Little Madam has been alternating between angelic sweetness and 360-degree neck-swivels whilst speaking in tongues.
She'd happily play by herself at daycare (who were okay with her being there as long as she wasn't too sick to enjoy herself) for a minutes at a time, then burst into tears because she can't pick the last raisin out from the bottom of the box.
Each time we've gone to see my mum in hospital (who's recovering nicely but feeling understandably fragile), TLM would reward complete strangers in the lift with the most gorgeous smiles. Then we'd get to my mum's ward and she would turn into Monster Child, who must be kept harnessed in her buggy or wander about the ward donating her cold viruses to post-surgery patients. No snack, drink, book or toy could keep her amused for more than about 3 seconds, but as soon as we left she'd be flirting with strangers again.
I suppose it could also be a case of familiarity breeding contempt (on her part, that is).
