 [ Symptoms ] is it normal for a toddler to hide things [ Disease ] toddlers can have a lot of odd behavior so i guess that hiding things could be one of them toddlers get into all types of mischief since they readily explore their expanding environment they think nothing of taking a steak knife out of the dishwasher and run down the hall with it when they are caught and disarmed they will collapse to the floor in a tantrum because you took their knife possession is important to toddlers so they may hide things so they can keep it for themselves it is not unusual for them to take car keys and throw them behind the couch or worse flush them down the toilet correct the toddler gently but firmly tell them about your things and hisher things focus on the behavior but not the child for instance hiding mommy is keys was a bad thing good boys or girls do not do these things and you are a good boy or girl these odd behaviors tend to be very temporary so hang in there
