Bottle warmers - I have two which were never used, upright bath seat which didnt have any underside to the bar which wraps around so the hard plastic was digging into her legs, tommee tippee bottles - gave her wind and the teats kept collapsing flat when she sucked (love Avent bottles and teats), and I also have a Quinny Zapp Xtra (out of necessity of having a miniscule car boot so it was the only pushchair available that would fit - it only just fits the collapsed chassis with no more room) and whilst its not awful, it is very flimsy and we have a 2nd sturdy pushchair for days out that lives in my partner's car. Unfortunately I would have to buy a new car if I bought a new pushchair!
