Graco Dreamglider

Does any one recommend this? My three week old has reflux and has to be held upright after each feeding. The issue comes when we go to lay her down she wakes up every single time. Some times it takes 3-4 try’s before she’s out. This mama is desperate for sleep and I came across this product. I like that it starts out inclined but then can go flat without waking her up. It is pricey tho so I don’t want to buy it and have her hate it. I’m also worried about how long it’ll be until she outgrows it.
