is so hard for my 3year old and he's so upset without it that I've let him have it back. Most of the time he's fine without it, but as soon as he's tired then he wants it. Last night we put it away in a special box with all of his other baby things, which he was fine about, but when it came to bedtime he was sobbing for it. Today, he was so miserable without it that I gave it back to him. Should I just be strong and let him go cold turkey or let him have it until he grows out of it hopefully before he's 20! Any tips on how to say farewell ?
