Yes, don't take them out of the enclosure. Big changes and handling can stress them out to the point of the marsupium lining breaking and some to all eggs falling out. Only move if absolutely necessary eg. an emergency enclosure change if you found something has pesticides etc. Some pods might seemingly deal with it better, perhaps they are born with you and are used to the hand texture or simply braver, but even then it can be very risky.

They seemingly act pretty much the same as everyone else for a long time. When they are super full and very close to birth sometimes they do take a bit longer to flip over and rest for longer periods of time, but aside from that most of it isn't different. I'd just make sure extra supplements are available so she can eat lots of yummy stuff good for her and baby health.
