I bought ds cot bed from Babiesrus. It is the I love my bear one. At the same time I bought the I love my bear cot bed set (sheet, blanket and cot bed bumper). So was the same make and obviously the bumper was designed for this particular cot bed (although I imagine it would fit most cot beds). This was about last Septemberish. Ds just turned 1 at the end of last December. Woke up today to find the bumper has torn (it was not torn last night and did not show any signs that it was about to) and ds pulling the stuffing out of it. No harm has come to him but he could have easily been trying to eat the stuffing (he's still at that stage). The bumper was still attached to the cot and I can only assume that ds was standing and maybe stumbled and grabbed onto the bumper as he fell causing it to rip, as I cant think of any other reason why the bumper would rip. AIBU to complain/get replacement/refund or should i treat this as natural wear/tear?
