Do I need to do anything to prevent estrogel spreading to other people?

I will start taking estrogel this week, hopefully to help with insane tiredness, joint pain, and an overall blah feeling.

One of my kids is still pretty small, so I pick him up, carry him, or hug him throughout the day.

Do I need to do anything to ensure he, or other family members, don't have contact with me while I'm using this gel? Or only for a short while after applying it? Thanks!

(Maybe a little weird question, but it occurred to me today, so thanks for any info!)
