Header image cuts off on iPhone/iPad

Hi, I’m using the WooCommerce Kingdom Theme. My header image looks good on my laptop, but when I look at the website on my iPad or iPhone, half of the banner goes off the screen.

I’m hoping it’s an easy fix. I tried asking the fine folks who created this theme, but it’s not easy to get an answer that doesn’t require me to have a Masters Degree in coding.

My website is: http://www.BabyProofPlace.com

Any help on how to get the website to look the same on all devices would be hugely appreciated! Thank you in advance!
