You obviously have a heavy responsibility being a dad. I can't say outside of being a fill in baby sitter with nephew and nieces visits. But you are the big parent and authority. Kids seem to need to hear things in small increments from relatives and friends to the family where nothing is forced.

Do not trust social services and look at your own network with who is around you. I do not say that lightly since I considered psychology as a main field.
With what is on T.V nowadays I try to keep the channel on retro television when kids come to watch. They are interested just the same.

My mother is in post acute care now with terminal cancer.
Everything from childhood sure rushes back.
