Some similarities but a lot of differences.
My daughter is now 5 which is the age I was when my parents divorced. Thankfully that doesn't seem to be on the horizon for DH and me.
DH is much more hands on than my dad was and I feel that's a trend now to have more involved dads. Obviously helped by a lot of people having flexibility to work from home in some professions. When my dad was living with us, I never saw him during the week, he had left for work before I got up and didn't get home until I was in bed.
Technology - obviously she has access to tech and entertainment possibilities that we didn't. We didn't have tablets, she does (actually its our tablet but she is allowed it on weekends) She has access to on demand tv whereas we had 3-5 channels and maybe the occasional video.
Social - just so much more stuff now. I don't remember any soft plays in our area until I was 10 or so (mid 90s), nor did I have as many extra curricular to choose from as she seems to. However my view may be skewed as we are much much better off than when I was that age so it could be these things existed but we couldn't afford them. I do find playdates aren't as simple as they used to be, like going to a friend's house for tea but I think Covid might have had something to do with that. We all forgot how to socialise for a bit.
School - I went to a state primary, DD is at an independent prep. Purely to do with the fact we can afford it, my parents couldn't (and I'm not even sure we had any private schools that close to us)
But some things are the same. She likes Enid Blyton, Roald Dahl and Beatrix Potter books. She plays with lego and little plastic action figures. She likes the older board games like guess who, hungry hippos and Ludo. I did think she was less able to entertain herself than I could (we are both onlies) but it's to do with how much is being thrown at them and us being so available whereas for me growing up with a single parent or being looked after by grandparents who couldn't play with me the whole time, I got used to it early. She is getting better at playing independently now to be fair as we have encouraged her and she does now enjoy her own company more.
