Hi, I have four DC youngest now 21. Each pair has different Dad. Both Dads didn’t live with us beyond toddler stage but saw once a week if lucky, no interest in their education or support as they aged.
The older pair see Dad maybe twice a year at DD1 instigation.Younger pair, one feels no connection and so doesn’t want to visit other feels obliged to see very infrequently.
Personally I feel you get out what you put in so DC are apathetic.I know they are old enough to make their own decisions but do you think they should make an effort?
