Over protective / trust issues

This weekend I am a bridesmaid in a wedding and will have to leave my 3 month old with daddy for almost two full days as I am so busy doing wedding things. Its the first time i have been away for more than a few hours and its totally stressing me out! We are having to figure out when i will be able to pump and how he can warm a bottle in the car or at the outdoor venue...and what happens when i go hours and hours without feeding her? My boobs will obviously hurt so now am having to figure out where and when i will be near an outlet i can pump!! This isn't easy, and on top of it i know daddy is great with her but as I spend most of the day with her while he is at work i have learned more about how to calm her etc and worry she will be inconsolable while im gone ( happened at the weekend and he just let her cry it out for 10-15mins til she passwd out) idk mamas help im just nervous and dont know how it can be easier for ebf babies being left with someone else? Is it normal to feel like your the only one that knows how to best care for your babe...
