Anyone have a Doc a tot or similar?

Does anyone have a doc a tot? I have a toddler and about to have a newborn in a few weeks so I was thinking a doc a tot might be nice for naps during the day? I could put him in the doc a tot on the couch or floor while I play with my toddler. But the doc a tot is super expensive, especially because they have different sizes so I’d have to size up each time he grows. Did anyone have one and was it worth it? Or something similar but cheaper??
