Hello, looking for advice/hints/tips. DS is 18 months old and I want to move him into his toddler bed in the next few weeks. I need the cot for my younger son who will be going into it in about 10 weeks, so I want to give DS plenty of time to adjust. I’m just worried about how he’ll be going into the bed. I had looked for zip sheets to help stop his falling out and losing the covers but they’ve been discontinued!
