I understand how you feel.

I nursed my son until his 2-year birthday. Just tell him because you love him that you'd travel with him, but you are tired, and you need him to plan a couple of stops to feed your baby. And you try to relax and take naps the rest of the trip.

Write down what you'd need to bring along and make sure you pack them in your suitcase. If you dont' write them down, you might feel overwhelmed.

Good luck!
