Advice for mom guilt

11 month old has been in daycare for 6 months now, but I haven’t been working full time (I’m a consultant and wasn’t staffed on a project) so I was able to do late drop off/early pickup and have a good amount of time with him each day.

Next week I start a new project working full time, and I’m feeling a lot of feelings about how little time I will have with him each day now. Where the guilt really kicks in though, is that I don’t want to be a sahm. Financially, I could if I wanted, so I’m actively choosing not to. I feel so guilty that I don’t want to be with him all day.
