My DH travels 50% of the time for work. My two-year-old is used to it now; all I do is just remind her when she asks that daddy is at work and will see him when he gets back home. We do try to FaceTime with him each day; doing it during meals is great because the kids are strapped down and you can just prop up the phone while your child eats and they can talk.
As for cramming it all in, I do pretty simple dinners. Nothing crazy elaborate, but also not frozen pizza every night. Baked chicken, pesto pasta, pancakes or scrambled eggs for fun. I get my toddler involved with cleaning as I clean. She loves to “dust” or clean windows with a dry paper towel as I do it or okay with her toy vacuum while I swiffer. I also have her help with laundry. She likes to throw things into the washer or dryer and I gave her tasks like finding all the socks when we are folding to keep her busy. Otherwise, you’ll have to use naptime or while she’s sleeping to get stuff done. And of course she comes with me on whatever errands have to be done. I am a stay at home mom so I can mow the yard and take out the trash while she is napping, so if you work you may want to hire a lawn service or hire a babysitter for a few hours on a weekend so you can get outdoor stuff done where it’s too dangerous to have your kid running around the yard at the same time.
It will totally be fine! I promise! Most kids at this age don’t even really realize one of their parents is not there or for how long that is
