After we tuck our 2 year old son into bed at night...?

i have a lil boy who is 2 1/2 he started doing that around two( same time he moved in toddler bed) and he use to try and get up only prob was that he wouldn't go too sleep til it was so late that he wasn't getting proper rest.. i did the keep putting him to bed w/o saying anything other then i love you and good night see you in the morning in a firm but loving voice ! it took around a week for him to get the point now he goes to bed w/o a issue.. sometimes now he gets to take a book to bed or ill here him talking to his animals til he falls asleep but rarely get out of bed unless something is actually wrong! good luck!
