Baby monitors

I’m wondering for the mommy’s who have 2 under 2 and you’re still using a baby monitor for your first, did you purchase another baby monitor for your 2nd kiddo. OR did you get a baby monitor that has the 2 cameras and the monitor that can split screen? I received a baby monitor from my baby shower but then I thought…do I really want to be hauling 2 baby monitor screens around? So what do you mommas have? And if you can suggest the 2 camera/1 monitor. Thank you in advance! 🥰🤗
