What will taking a sabbatical to focus on being mom do to my career long term?

I just returned from maternity leave, where I spent the last 6 months with my newborn and toddler as a full-time SAHM. My role, team, company (we were acquired), office, and overall company culture has changed for the worse while I was away. While I never wanted to be a stay at home mom, nor did I ever envision myself not working in my career in marketing, it feels wrong to be back at work. I am so grateful that I was able to take a long maternity leave (6+ years at the company and I used up my vacation time to get to the beginning of the school year) and am feeling guilty that my heart just isn't in the job anymore. I am debating taking time off: perhaps a year (until the start of the next school year), maybe just another 6 months (until my son's first birthday), to be a SAHM. I am not sure how easy it would be to jump back into the world of marketing, or if I would be able to re-enter at my current level. It's been 7 years since I interviewed for a position, but I have been a hiring manager myself for that entire period. How should I navigate this? I do not want to leave any ill will or burn any bridges if I do leave. Am I better off giving it a month to see if I feel better? Or do I listen to my mom intuition and rip the bandaid off ASAP, lessening the impact on my kids? Or, should I try to find a position part-time or that is fully remote to carry me through this time? If I do choose to leave, I would give my company the choice of my notice period (I am contracted to 2 weeks but would allow up to a month if they need the coverage). Note that I am extremely grateful for my financial situation that is allowing me the privilege to make this decision. It won't be easy but we live very frugally and below our means already.
