kids sharing rooms

Amarilis
I have a 4 year old and am currently 34 weeks pregnant with another girl, we live in a 2 bedroom apartment so they will be sharing a room, I am feeling stressed because I feel like my daughters stuff takes over everything to where we have no room for the new baby. Is anyone going through this? Or have any ideas how I can make it easier for them to share without my older daughter feeling like her space is being taken over, if anyone has any pics that would be helpful too TIA!!!
