How can I keep our 22-month-old hydrated, as he spits out everything he drinks?
Yes, he will stop doing this when he realizes this is not the best way to get your attention. Many behaviors at this age are the result of a toddler
wanting to show everyone he's in control. And often these behaviors are not the most pleasant. You might try giving him attention by allowing him to choose the container he wants to drink froma paper cup, a blue cup, a red cup, etc.
If he continues to spit out the liquid, just matter of factly say "We don't spit." If he continues to spit, just take the cup away and say "We're done." Then go on to the next activity. If it's mealtime, let him finish eating and don't worry about liquids. Be sure he watches you as you drinkneatly! Toddlers
really want to please their parents, so eventually he'll figure it out that this spitting game does not please you and will not get your attention.
Keep in mind that many foods he eats contain water, and it is very unlikely that he would get dehydrated. You can also offer juice Popsicles as extra liquid. Good luck!
