The best way I have found to raise a baby is put it on wander inside a Dino leash and don't leave render range. So fine things to do around your base and don't forget to cryo them if you need to go on I meet run or they will die quickly I know I sacrificed 5 of them to the Ark gods.
If you’re playing Genesis Part 2 and you come across a loot drop open it and one thing i’ve found on official is that some drops give lots of pipes, generator wires and water irrigation pipes which is basically free food for the gachas! You can also grind them for resources and craft them into other items/structures of your choosing aswell! Hope this helps.
