How young is too young for a sticker chart?

[ellanatal]

My ds1 (2.1) has become a nightmare sleeper having been the perfect sleeper for most of his young life - i know its all coincided with ds2 coming along but i really want to sort it out! He's been faffing on going to bed but more of a problem is wakening in the night and taking hours to settle back to sleep. All his teeth are through cause we blamed it on that for a while and he's not hungry (he eats like a horse) so we think he's just playing up.

Is he too little for a sticker chart?

my dd2 loves stickers as her big sister gets it - so I put up a sticker chart for her last week - she is turning two next week.

Thanks eidsvold! I've tried it this morning cause he slept last night and he seemed to love putting the sticker on but i dont know whether he'll understand its for sleeping all night (although we both said it about 10 times!!)

just stick with it - I give dd2 stickers for all sorts of things - just tell her and let her pick the sticker.
