Both families I am playing right now have adopted kids.
The first has 6 kids... 4 bio girls and two adopted boys. Actually the dad went out and secretly adopted the second infant boy while his wife was at the hospital giving birth to their youngest lol ? and they already had another bio girl who was still a baby at the time so the 3 youngest are very close in age. They are tots now though. (they have two kids and a teen as well)
The other household was done without feature. I was playing a sim from toddler up having her accomplish everything. Her mum died when she was still a child so I created an adoptive mother for her in cas lol
