It had been a week since Mummy and Daddy decide to let Yishion sleep on his own mattress on the floor rather than on the baby cot. The reason are Yishion already able to climb out from the baby cot and the space are not enough for him to turn around.
After he started to sleep on the mattress, the frustration that we faced are he would turn around too heavily until to the floor. We already place 2pcs of mattress on the side, but he still would sleep until to the floor. So, mummy and daddy would need to check on his position in the mid-night. The most funny thing is he would able to sleep on the "COOL" floor without any support mattress.
