@nicolestevens84 We have been going on trips since our kiddo was just over a year. His first trip was a train ride to Liege, Second a flight to Amsterdam, then to London for a friend's wedding, and finally to the west coast of the US to visit Oma and Opa and to Burning Man. All between 1 and 2.
For his second birthday, we went to Paris mostly for us, but on the day of his birthday we went to Disneyland Paris. He then compared it to Burning Man, then we went to Athens. Then covid hit. We were still able to do Talinn, Estonia for my wife's birthday and We did Thessaloniki in October that year.
For his 3rd birthday, we stayed at home because of covid. That summer we went to Prague by train, Paris Disneyland again in the fall and spent most of our time there. He remembered doing stuff in Disney Land when he was 2. Un-fun trip; In early october right as we got back from Paris, we were notificed that a friend had killed herself. We were planning on visiting in late october with said friend. The trip that was supposed to be to see and spend time with her, Ended up being the trip to go to her funeral. Then in December because our yearly passes were expiring we did a quick trip to Disneyland Paris with a couple of friends.
In 2022 for his 4th birthday, we did a small resort near our home town.
Tropical Islands which is a cool resort built in a former Zeppelin Hanger He remembered the cake we made and asked for another one just like it for his 5th birthday. We did Porto, Portugal for my birthday in February. In April, we spent 2 weeks in the US because we got hella cheap (like a 900 euro round trip for the 3 of us) and did a big road trip with the grandparents. Went back for Burning Man in August... He remembered leading up to the moving house (we have an RV still in the States for Burning Man) We also did another couple of trips to the UK.
In 2023 we did Disney Land for his 5th birthday, and then did Egypt for my birthday the next month. Went to the Uk for my wife's 40th with friends, then to Burning Man. Also not included are fairly regular hops to London, It is really easy to go there because we have a standing invitation at his uncle's house, so we just need to get there.
So far this year for his 6th Birthday we went to Spain. My son
requested Spain, we had friends there so we went and stayed with them. Then I went to Flordia for my birthday, My wife and him went to Ireland and we are all planning another trip in May to the UK and in July to the UK for my wife's birthday.
Not sure how much he remembers He will randomly drop "I have been there!" when he sees stuff in books or online. Of course, the souvenirs which we let him pick he remembers vaguely where we got them, But we sure as fuck remember and we have the google photos accounts of pictures of him sleeping in front of landmarks, or playing around them.
The kid (by our privilege and where we live) has been to more countries in his first 6 years than I have been to before I turned 30. And even then the only countries he hasn't been to that I have been to are Canada, Mexico, Belize, and Japan but we want to do Japan with him.
You asked what age is worth it... I think any age. One of my favourite pictures of us is me walking through Liege with ice cream and him in the baby carrier on my back and we are both SMILING just having a great time.
