Evening routines?

For those of you with little kids (toddler) and work full time what does your evenings look like after work? I’m in such a funk and maybe overwhelmed and I think it would be nice to hear I’m not alone and get some inspiration from you all. My husband is in the military so his schedule is always all over the place but I’m off at 4 then I go pick up my son from daycare, get home, start dinner, eat, then a little down time before either bath or just right into bedtime routine. I find I’m just so exhausted and don’t feel like doing anything but I feel guilty I want to spend quality time with my son. The weekends are easy and we always go do something as a family and stuff but the week days are killer. My sons bedtime is at 7 so we don’t get much time on the week days. Thanks for reading
