We modified our hammock so Jovie was at the bottom and not the middle,... we put a wheat bag under one side of the mattress so it would weigh it down and Jovie's head was above everything else so her reflux wouldn't hurt. We tied up the sides and zipped it up on the bottom and put her down near the bottom... so I can't help with it being a problem, but that is how Jovie always slept in it.
