Best if you have 2 or more, better yet, have 2 or more and a few nice steady does (or wethers) that tolerate the kids.
I only once bought 2 kids that were still on the bottle. I only wanted 1, but got 2 since a single baby is a pain. I had them sleep in a safe and segregated spot, but during the day I had them with my milk does. Being with the does they immediately had to learn how to integrate into the herd, and be goats. My does were good to them.
If you do not have any adults, or your adults hate kids... then besides making sure you have at least 2... you are stuck with teaching them what to eat and not eat... and what behaviors will not be tolerated.
Make sure you teach them not to bite, or be rude, and where they are supposed to sleep, and live.
Goats are pretty smart and will learn quickly as long as you are both clear and consistent.
Rarely have bottle kids. I prefer mom raise them to be a goat. The few I have had, I have left with the herd. One was a triplet mom cared for but wouldn't nurse it...just other two. This year had a doe kid preemies, one didn't make it. Other I bottled but after 3 days it was in barn and snuggled with other kids. At 3 weeks it was about size of a pair of twins born then and it adopted that mom. . She wasn't thrilled but he was black like hers and very stealth. I continued to bottle and check tummy for fullness for couple weeks. Now she's more tolerant and the three are growing well! Nice she's a heavy producer.
He is very tame to handle but, not obnoxious. . His twin brothers come with him for attention. Homemade trips?
