Like me, a lot of littles have speration anxiety when they're small (and maybe while they're big too. Depends on the person.) So, here are some things you can do to help your little relax a bit more when you have to leave.

🧸Tell them you have to go soon 5-15 minutes before you have to leave. It's good to have your little prepared when you have to leave instead of going "Kay I have to leave bye." And leaving them there all anxious and stuff.

😰 Set times when you can talk to them. Same reason as before, this is to have them prepared. This might even be a better alternative if you can because then when you have they have something to look forward to (for when the next time you talk.)

🧸Give them a stuffie/next time they get a stuffie ask them if you can name it. This is good for when you leave that they have something to remind them of you.

😰 Same thing as before but not stuffie. Get them a blankie/pillow/comfort idem.

🧸Give them tasks before you leave. This'll keep their mind busy (atleast for a bit) while you're gone.
Examples:
-Color [number] pictures
-Make a list as many red things you can find
-find as many flowers as you can
-Give each stuffie a hug and kiss
-Do a puzzle
-Get to [# level] in video game
-Play outside for [however long]
-Watch however many Disney/Pixar movies
