kellee - never heard of toddlers with dark circles under his eyes but if it runs in the family hopefully it isnt anything to worry about - is charlie sleeping well at night? how is he going in his big bed? im tempted to move eliana into hers (i got a disney princess toddler bed that uses her cot mattress) as when we were away she slept on the floor & didnt wander too much & isnt liking her cot atm
