Most likely, no. If your baby is starting to sit up & pull up on things, I would be afraid that he or she would fall out of it. The cradle was ideal for my baby when he was first born until he started getting more mobile. Hope this helps.

Putting bumpers in this cradle would be a tight fit and would be unsafe. Bumpers are bad enough in full size cribs but in the close quarters of a cradle it would be even more of a suffocation hazard. The AAP recommendeds strongly against having bumpers, comforters, or pillows in a baby's bed.

I assume by "rung" you mean the vertical rods on the two side panels (the ones to the right and left side of a lying baby). I just measured it with a tape. The inner distance between the rungs is 1/8" less than 2" (i.e. 15/18 inches). Thickness of each rung is 1/8" less than an inch.

I ended up just looking up cradle mattresses and bought the one with the best reviews. The one I got had an extra thickness to it but it was two years ago so I can't remember the exact one.
