I really don't understand why holidaying with small children is stressful but there's so many threads on here about it regularly so obviously you're not alone. Possibly just down to personality, expectations, individual kids, location etc
I honestly live for holidays, even more so with our children now we have them. There's nothing makes me happier. I find it so much easier than parenting at home (which can be stressful) as both parents are available, no work, nicer weather, activities and things to see and do. It's parenting but a million times better as it's just all the fun stuff and you don't have to worry about bedtimes or nursery runs.
We had a few with DS abroad before Covid hit, then we had DD and so far we've done:
Static Caravan park in the Lakes (DS 3 and DD 5mths). Lovely holiday, we did the zoo, Peter Rabbit world, the Aquarium, boating on the lake, steam railway, swimming every day. Was the perfect week away for a first holiday with two kids.
Menorca (DS 3 and DD 7mths). Absolutely loved this, did the kids disco every night so kids slept great and slept in every night. All inclusive so they tried so many new foods, lovely chilled days round the pool or walking to the beach. DS made friends who were still in touch with.
CenterParcs (DS 4th Birthday and DD 10mths). Went for Winter Wonderland, did horse and carriage ride, loads of activities, swimming, walking. This was absolutely magical. The best Christmas experience ever.
Disneyland Paris (DS 4 and DD 15mths) It's Disney....what's not to love! Both children had the best time of their lives, absolutely loves the rides, characters and shows. Even stayed up until midnight and watched the fireworks.
Next month we're going to Salou (DS 4 and DD 18mths). Again, swimming, kids discos, trips to Barcelona to the Aquarium and parks.
I'm sure these holidays sound like some people's worst nightmares BUT if you plan with the kids in mind then you should have a good time. Hopefully that might give you some ideas 💡
