Applied for work

I just applied at my old job. I first started there back in 2019 for their holiday season and they ended up keeping me on. Then COVID hit and since I was part time, they let me and hundreds of other part timers go. Once everything settled, I reapplied in 2021 once my daughter turned 1. My daughter was still breastfeeding so my partner had some trouble being at home with her. He’d blow up my phone while at work saying he couldn’t get her to take bottle or eat anything. I only worked weekends. I was there for about a month and for every shift I’d have to leave early because my partner was desperate. I ended up having to quit but I’m pretty sure I left a bad taste in their mouth. I reapplied today at the same company but different location and didn’t add on my resume that I worked at my old location in 2021. I know they’ll most likely call them for reference and I’m so nervous that I won’t get the job. I loved working there. I was so happy doing what I was doing. I’m really hoping I get another chance.

To add: reason I left it off is because I worked MAYBE 3 weekends in total and only for about 4hrs each shift because I’d leave early every time due to my husband needing help. I didn’t count it as even working so I just thought that maybe they wouldn’t count it ? I don’t know and I think it might be too late to change what I put on the resume since I’ve already sent it in along with my application. If they do call and ask about it, I’ll be honest and let them know my thought process on why I left it out and also explain my situation as to why I had to quit and leave shifts so early while also reassuring them that my daughter is now older and is easier for my husband to handle
