Congrats on your hoggies YB! They don’t play Happy Families at all I’m afraid. They will only hang around with Mum for a very short while (couple of weeks?) and then strike out on their own. If you have other suitable nesting places then you might be lucky and one of the kids may stick around but essentially they like to be alone most of the time.
If you continue providing food and water then they’ll remember where it is and may well keep coming back for more but they don’t really do loyalty. Some of mine have been visiting for years but have never lived in my garden so I’m just a useful service station on their nightly rambles.
