No worries, we specified about cloth so they bent the bar more so could fit, not sure if you are doing this but we used to find easier to put her on front to feed through and she got extra tummy time.
We also changed nappies face down, MUCH easier to get the nappy on (with a few flips from back to front). We'd start with Bailz on his back, clean up as much as possible, then flip him over to clean from the other side and then feed the nappy through, flip back over and do up the nappy - we soon became experts at it
