How did you make it through your 3rd trimester with a 1 year old?

I am four weeks into my 3rd trimester and the overwhelm is hitting me so hard. I feel completely overstimulated from the moment I wake up to the moment I go to bed. My 1.5 year old is feeling like such a handful to me and this makes me feel guilty. She is so full of energy and wants to play/climb/be held/be read to/engage with me constantly. She also loves to run around with food in her mouth, spit on the floor, and is constantly spilling things. She also of course got a cold over the holidays and has been simultaneously hyper and grumpy and extra needy this week. My husband is amazing and has signed up to be what we call "parent #1", but honestly she is a two parent job most of the time, with all the cleaning up that has to be done in her wake. We also just moved into our first home about a month ago and are still living out of boxes. All i want to do is unpack and organize our things so that I know where everything is, but I'm so tired I can barely get through two boxes a day. The nursery is piled high with boxes and it's stressing me out. I feel guilty that I'm counting down the days until daycare starts again. Any tips for getting through these next 9 weeks without ripping all my hair out?

EDIT: thank you all for the advice and most of all the solidarity! Yes we have daily routines and the house is safe for her to move through. She is a great girl just very social and always wants to engage. Sometimes even ms Rachel doesn’t keep her occupied for more than 5-10 mins. She goes to daycare which is beneficial for all of us but the winter holidays had her home for 2 weeks straight and I got to the end of my rope / exhausted from the holiday run around. Thanks again for listening 🧡🧡
