As a former stay at home parent, my answer to this is: it depends. Definitely do a weekly check-in and listen to what your partner needs in that moment.

My needs changed a lot over time (sometimes week-to-week!) especially as a breastfeeding parent. Kids go through developmental stages which can be anywhere on a spectrum from delightful to really really frustrating for the one who is with them all day (and perhaps night!). Whenever my husband checked in with compassion and the intention to support, it was helpful.

In terms of the practical, some weeks I needed things like help with making food (which in my husband's case meant getting takeout! 😂) or taking an extra task that was typically mine. Other times it meant listening to me vent.

We also have assigned parenting duties (he's the bather and evening toothbrusher) which typically bought me 20 minutes every night, and a "mandatory" "give mom 2 hours alone" period no matter what on either Saturday or Sunday. Alone time is something I need to function, but it's hard to come by as a SAHP. Your partner will need to hold boundaries on taking what they need when it comes to time for themselves, which may be particularly hard if the little one (or ones) has a strong preference for them. I personally really struggled with this both when I was a SAHP and even now that I'm back to work.

And please be real with yourself. There's no such thing as "even" in a partnership. Sometimes you're giving more and sometimes you're taking more. Striving towards an equitable relationship is admirable, and your partner is lucky to have someone like you!

Ada Twist, Scientist! It's about a little girl who is curious and with her two friends forms a hypothesis to test. Typically, each episode teaches some kind of physics or chemistry concept. My now four year old daughter has loved it for a year - so absolutely suitable for a 3.5 year old. Please follow up later to tell us what you found because I'm also interested in the answer to this beyond the typical PBS shows we watch.

My workplace is also pushing long-term for Power BI (and/or some kind of Amazon tool attached to an aws data lake), but you are right, it's not nearly to the level of Tableau. My office will be sticking with Tableau for the foreseeable future.

I also have a lot of interest in the open source space. In addition to Apache SuperSet, I'm keeping an eye on the development of both Grist and Redash. Depending on community interest and support, I see these becoming potential open source alternatives to Tableau. I currently self-host Grist and am quite impressed with its potential.
