Need some advice... help!

Savannah • 23. Married. Girl mom x3

So I’m due March 18. I have an almost 3 year old and my step daughter is 12.

I am going to be MOH in my best friends wedding in June (so excited!!!) but I live in VA because my husband is military and she lives in our hometown in FL. Well she is trying to plan the bachelorette party and bridal shower and obviously I would love it be in attendance for both. She is wanting to do it at the end of April or beginning May. She wants me to commit to saying I can make it but I am so nervous. There is no way my husband will be able to take off to watch all of the kids so I will have to bring new baby and 3 year old with me for a 15 hour car drive...... I am trying to explain to her that it might not be do able. All I can think about is it being literally 4 weeks after I give birth. Baby is gonna be on a crazy sleep schedule and I will be too. I just don’t know what to do. Try and make it? Or just write it off now so I don’t get her hopes up...
