You have to make it so it feels ok, to leave your son for a few days, and so it feels ok to go to work and on travel. It might be different than people before you have done, but you can make it so it feels ok.
No matter where you go, you'll always be with your son.
When you make your time for him, and create good memories, that's very valuable. You are not like other mothers, you're different! It's ok.
