How long did anyone use theirs for? My babies are 23 weeks and we only use it for night-time feeds so it hasn't been bashed out ... it's sprung a puncture somewhere - groan. Have a nasty feeling it's around the air hole so would be impossible to fix. Am totally browned off as it's handy for feeding in bed ... I use a v-cushion downstairs but in bed that needs to be propped up with what feels like 100 pillows. So, please make me feel better and tell me the babies will have outgrown it in a few weeks anyway - or that it's under warranty!!
