We've had to start putting the side of the cot up when Kynan's in it as he's just started sitting up by himself and reaching out to pull himself up on things. The problem is the side is really noisy when it's raised and lowered and wakes him up. I can't leave it permanently up as Kynan needs me to be right down next to him when I settle him. Anyone got any ideas on how to stop it making so much noise? It's a timber cot and the raising/lowering bar thingies are metal.
