I know that crib mattresses have to be firm, but my DD is almost 6 months old and I honestly think that she hates her crib because the mattress is to hard. I have the Sealy spring mattress that was recommended in the BB book. I also have the inclined to sleep positioner and she seems to sleep so much better on that because it cradles her body. But I know that you're supposed to discontinue use if your baby can roll over which she can do. So my question is...is there anything you can do to (safely) make the crib more comfortable? Also does anyone use their positioner past the roll over mark?
Thanks
