Dinner times in Sweden are generally on the early side, with 16:00 not being unheard of in families with small children, and 17:00-18:00 being a common time to have dinner.
Usually we let the baby having his meal first (he is 8 months old), when everything is said and done, we put the baby to sleep. Then we have our dinner in peace or do whatever we want.
That being said, I just thought it's super early outside based on your picture. What you're saying is totally reasonable and I completely agree.
