My nearly 3yo has been complaining of a sore knee over the last month or two. I guessed it was because he'd scratched it and was looking for sympathy, you know how they do, and so we carried on the 'pretense': we'd kiss it better, that sort of thing.
Now, last night, he woke up crying twice and complained he's knees hurt him. I had to snuggle up in bed with him for him to go to sleep - he was that upset. Now, it could have been nightmares/too hot, or something else, that woke him up and he just complained about his knees to gain comforting cuddles. Or it could be that his knees really do hurt.
MIL had early onset arthritis (early 50s) so I'm a teensy, teensy bit concerned. It occurred to me also he might be experiencing growing pains - do growing pains even exist in toddlers??
