So me and my ex split up. We have 2 kids together a 10 year old boy and 6 year old girl.
The ex has a new partner, approx 6 months into the relationship now. Not quite moved in yet together but spending quite a few nights at the ex's house each week.
I have always been protective of my kids when travelling in mine or other peoples cars.
The nan (mum of the ex) is on quite a lot of medication. Takes around 20 tablets a day. Maybe more. Have always restricted their travelling with her to a 2 mile trip on a 30mph road where its down to a supermarket and the roads are not really busy. They use my car seats whilst they do travel in her vehicle.
Wherever possible I drive them to their destination if meeting up with school friends after having invites to parties etc.
The ex may have gone along with this while we were in a relationship just for my sake.
As it now turns out they now travel back and forth over a 30 mile journey each way to visit friends and family in their nans car. Nan driving with the ex and 2 kids in the car. With car seats.
The problem is the new partner of the ex, only has a 3 seater vehicle. Its like a car with 3 seats in the front and then van part in the rear. Not like a transit size vehicle. Like an estate car. Like a citroen dispatch - the smaller type.
The new partner has apparently picked up the kids from their school or taken them to school in the said vehicle WITH NO CAR SEATS. Yes the journey is less than a mile each way. But my kids are 10 and 6. The 10 year old is still under the minimum height.
I do not know if there is an airbag in the passenger side so that would be a concern as well. I believe kids are meant to be in the rear of vehicles when passenger airbag is active.
What happens if this becomes a regular thing and then they will be doing the 30 mile journey to family/friends next?
Do I say anything to the ex or am I being unreasonable?
