Can someone look at both these meshes please?

Hi, I really love MAX 20 child bedroom kit so ive made a crib and toddler bed to match the bed in this kit (Its just for my game, i dont upload any of my work anyway) however i have no idea how to do rigs etc, ive tried in the past but cannot do it to save my life and also they look strange in game. You can edit it if you like. Thank Youu
