Girls, hello! Could you please tell me how to get my child used to the stroller? Every trip is an ordeal! I take a bunch of toys with me, and each one takes him for a couple of minutes and everything! I can't fasten him in the stroller, he wriggles out and runs off everywhere ? After waking up at home, we play with him to release his energy, and then we go outside an hour before bedtime. Has anyone had this situation? I hope it will pass and he will walk calmly.
