Im just curious....and expecting to he shot down. But is it dooable to boost the height of the mattress in the sidecot? At ther moment the mattress is about maybe 3 inches lower than ours. I can't raise the unit itself as there is a lip on the dropside which is currently flush (i saw that sad report about the consequence of this being higher). Ideally though id like the cot mattress higher so I can lean in and feed DS. Is that possible if i use blankets/something underneath? Or does this effect breathability. After c section i am uncomfortable lifting 3 week old ds in and out all night (and he doesnt sleep well) he has a sleepyhead but only really likes being on his side which we also cant do
