Spacesaver cots are good for an upgrade. Or a travelcot
My LB is in a Redkite Dreamer crib, it's the same size as a travel cot and can be used as one but the side comes down to use it as a next to me, he's been in it since birth and still has plenty of room x
We are in a similar position with our baby outgrowing her moses basket. We are planning to get a travel cot and then buy a better mattress for it for the time being
