We've been wondering lately when to take the sides off Zachary's cotbed.. The trouble is, he is such a restless sleeper that I'm concerned he'll fall out within minutes of going in. He likes to have something pressing against his head, so will worm his way up and down the cot until he's found the ideal position. When he wake in the night, he rolls around a bit until he's comfy again. Is this something I need to just grin and bear with strategically placed padding on the floor? Or should I wait until this phase is over (and when is that likely to be lol)?
