Els zoekt oppas - oppaswerk / oppassen in Rotterdam

Dutch mum, working as Assistant Professor at Erasmus MC. Icelandic dad, also in research. Our son Moses (almost 4) predominantly speaks Dutch and he understands some English and Icelandic. He loves playing with cars, building, reading, chatting and playing outside. He can be shy at first, but he is quick to warm to people when they are genuine with him (i.e. don't try too hard). He goes to daycare 3x per week and is quite social with other people and he tends to be happy with babysitters / his grandparents. He sleeps well in general (19.00-07.00), so evening babysitting tends to not be a problem. Primarily I am interested in a babysitter occasionally for evenings so we can go for dinner. Perhaps in the future I'm also interested in a few hours in the daytime (weekend) or pick up from school / afterschool. We have an Urban Arrow and normal bike with childseat that could be used for transport.
