We just bought a travel cot for regular home use. I know they’re not designed for this but space wise we have to. We’ve bought the Joie allura because it’s what they had at Argos (we had to get it quickly as she suddenly learned to pull herself up out of nowhere so the next to me suddenly became unviable) and bought a cuggl travel cot mattress to go with it. Baby is 8 months. I’m confused about the rules of travel cots and mattresses. Some of the internet says a baby shouldn’t sleep on a travel cot base for more than a few days because they’re not supportive enough for their spines so in theory a proper mattress on top should be better. Some sources say not to add a different mattress as this can be unsafe. There are no gaps between the mattress and the cot sides. I’m so confused about what we’re supposed to do.
