School runs

In a dilemma my kids go to a school that I have to drag my 5 kids to (school runs) so I applied for a school just down my road my daughter got a space as she's in year 4 but my son didn't whose in year 1 as the class is full however my other daughter got a space for nursery in September as she's already three now I accepted the place for near my house however I still have to do school runs for two schools as my son is on waiting list. My hubby is very angry with me and doesn't want the kids to go separate schools. His very negative saying my son won't get a space if his on the waiting list and he could wait for years...I'm due with my 6th child and my brother will help take kids to school as he is a teacher in the previous school .I just thought it would be easier for me if kids went to a closer school as I don't expect my brother to take them for a whole year in the other school ... I don't know what to do please help me
