DS (3yo) seems to kneel almost all the time -- when playing, eating, etc. I almost never see him just sitting & he has trouble getting into a cross-legged position. Does this have the same concerns as w-sitting or is it normal/OK? If he's not kneeling, he's standing. He CAN sit, legs straight out, in fact that's about the only way he falls asleep -- he hates hates hates to lay down. So maybe sitting puts him to sleep so he chooses to kneel, IDK. He also complains his back hurts once every couple of days, I don't know if this is at all related. What positions does your toddler spend most of the day in??
Co-sleeping is really wonderful when your child actually SLEEPS!!
