I’m writing this, sitting in a hotel room with the kids as my wife is outside chatting with her family.
Family or friends with can help quite a bit. Just someone there to take up some of the kids attention is really all you’re asking for. If they want to do more than that, that’s good too.
10 mo old is rough. I’d say, plan to be within 15-30 mins of a hotel for most of the trip. A lake/pool seems like a good option.

Do play dates with the same kids. Diff ones can be a lot.
It helps if there’s something there that kid likes. And if you can lead the conversation.
Look at all these pretty toys. My favorite color is blue. What’s your favorite color, Timmy? Max’s favorite color is green.
Etc. etc.
Feeling involved in the convo is good even if they aren’t speaking
Take him to a lil kids park as much as you can. Like every weekend. When you’re there, be on the periphery and encourage him to go play with other kids. Don’t hover right next. It’s ok to make the intros and then go hang on a bench. Idea is to get him playing with other kids by himself, getting into lil disagreements, dealing with kids that aren’t nice, etc.
The sleep training method I used was:
Now I’m (M) able to put in crib, sit on floor, and shh until they fall asleep on their own with minimal crying.
Most parenting books seemed to be summed up as ‘It depends’. There is a frustrating lack of empirically derived books. Best I can offer is talk now about parenting philosophy with spouse - e.g. how much crying is acceptable when 1 yo before you have to go comfort? When kid falls down do you swoop in or let the kid manage? Keep to that philosophy - kids hate flip-flopping on approaches


So the common plastic pump you see in every soap dispenser has two parts - the part you screw onto the soap container, and the piston thingy, above that, that you push down to get the soap to spurt out of and into your hand.
If you put something above the screwy part, on the lowest part of the piston, you reduce the amount that the piston goes down. And reduce the amount of soap that can come out.
Yes to the milk vs solids. Kids are smart and they know if they can get the bottle they will skip on other foods so they can get more of that.
My 3 yr old niece kept getting a big glass of cows milk before bed. As a result, she wasn’t really eating dinner. Was underweight. They cut milk out and suddenly she’s eating a lot more.
OK. I recently had to go thru a lot of this and here’s my experiences. Every child is different… But there are some points here I think I can help with.

Seemed to fuck up one of the pumps I had.
