Hi mums - FTM here and just set up our second hand chicco next2me magic evo and one side height adjust seems to be faulty meaning the next to me mattress is 13cm lower than the top of my mattress. I get that it will be more awkward to put baby in/take baby out but is there an actual safety risk to my mattress being higher than the next2me that I cannot use it? Thank you 🙏
