We are buying a new mattress and have a 3 month old, we'd quite like a memory foam hybrid but can't really find any info if this is suitable or not if we have her in bed with us? She spends most of the night in her own bed but inevitably joins us for the last couple of hours. She's going to be doing this for a little while yet if my older two are anything to go by.
It feels like it wouldn't be great if she sinks in. Any experiences?
