Working at home while taking care of toddler

Hi all.. just feeling very lost at this moment. Have anyone ever being the main caregiver and running a biz? I’ve been doing so the last one year and I think I did badly in handing my work. Esp when he’s now at the stage of a lot more active etc. ive got a helper but she’s new so i bring them whenever I have appts .im very hands on in both work n baby, but I’m very pressurized everyday as I can’t perform well at work anymore.. ;( felt like I am really not capable and I really feel like giving up on my biz. 😭😭
