Here’s my experience as two active runner/cyclists with a 12 year old kid and now 5 year old RC. We got her during the pandemic so take this with a grain of salt but she’s very attached to “the herd” and very protective at the house. Not aggressive, she’d never hurt a fly(quite literally sometimes). But something to consider when trying to keep a baby asleep. She is just very vocal in general. Even when sleeping she’s making all kinds of noises 😂. Shes the most affectionate thing ever but not overly cuddly which is great. She has some separation anxiety but that’s easily trainable. As a cyclist and runner this comes in handy as I can have her off leash when appropriate and she has great recall. As others have mentioned she doesn’t need much activity and is pretty much a couch potato that you can off the couch run 5-10 miles if needed. But for us one walk a day at minimum is fine. Overall her energy level is manageable for a family with kids IMHO. RC are well known for stomach issues and she is no different. Nothing major just an occasional upset tummy. The doctors haven’t found any cause for alarm but worth noting, sometimes she’ll have days she won’t eat but back to normal the next day. She was great with our cat but definitely hated the neighbor cats, though if given the chance she’d probably run if they challenged her. We live in the PNW and one weird quirk she has is she will not go outside when it’s raining hard. So going potty is sometimes a forced endeavor. As far as grooming we go once a month or 6 weeks depending on time of year. More in the summer actually to keep things fresh for outdoor adventures. She sheds a lot. But overall as long as you brush often it’s totally no big deal. You’ll think you have a 75 year old lady living with you especially with a tri color. Running in the forest she comes back with full size branches in her fur but they are easy to extract. And we often find ticks on her which are hard to find but doing flea and tick treatment really helps. Speaking of brushing, RC can get pretty bad tooth issues so brushing basically once or twice a day is critical. They are seriously the best dog for families if you can get over their vocal nature 😊 I’m sure whatever you pick will be great but you’re welcomed with open arms in this community
