Hi I am due in Dec, DS will be 19-20 months. Do I need to buy a second cot for the new baby? DS is 13 months and not yet walking. He is in a baby sleeping bag as he is a very restless sleeper. Everytime we put him to bed he is standing up on te side if the cot before we are at his door to leave. I know theres still 6 months but I just can't imagine how him in a single bed would go. DH thinks buying another cot is a waste of money though.
