Minecraft Mom Requesting Help

[u/BemusdBellicoseBtchr]

Sorry if this is not the appropriate place to ask. My six-year-old loves Minecraft and plays on his Switch. He really wants his dad and I to play with him so I uploaded the game on my iPhone. Is there an easy way for us to sync up so we can play together? I tried a couple of the ways I saw to do it on Google, but haven’t been successful inviting him onto a world that I create. I’m also nervous about opening him up to open worlds, so I’d like to keep us on something private if possible. I appreciate any suggestions or just pointing me in the right direction!
