We have a Joie commuter travel cot (from baby bunting) that we've been using with our 20mo since she was about the same age. The bed floor zips up about half way up so that bub is closer to the top of the cot, a bit like a bassinet. It also has a change table attachment that is really handy for changing and dressing 😊
We just used a porta cot (granted it was from 12 weeks) but she loves it - it’s a Phil and Ted one that is super light weight / small so we use it all the time when travelling
Check the manual for your pram bassinet - some are safety rated for overnight sleep 😊
Kmart has a great porta cot with bassinet option that is safe sleep appropriate
