P.K.
My granddaughter loved her nap nanny. When used correctly it is great. I would not suggest putting a six month old wiggly baby in it. 35 years ago, my kids had a version of the "nap nanny.". The difference In the two was mine had sides that were high. The nap nanny does not. I can see that as a problem if baby not strapped in and is a wiggle worm. If money is an issue put him in car seat. If you plan on other babies it may be worth the investment.
