We have this crib for my 20 month old and just purchased a second one for our newest addition coming soon. I am not happy with the mattress I bought the first time and it got a tear in it randomly. So what is a good mattress recommendation? Would prefer it to last as long as possible as the crib comes with the parts to make it a toddler bed and I don't want to buy a new mattress every other year. Any recommendations for Target ones as I could use my 15% off discount code for it lol? Thank you😁
