I admire this father’s apparent devotion to doing what’s best for his quints, but with their fragile health history, pushing them uphill in a buggy does not seem the smartest thing to do. I’m surprised the mother even let him do it.
Good luck to the family.
We had a premature daughter, and by the time she was 1 she was a very robust little thing who would have been as capable as any other 1 year old of being pushed in a stroller for 27 miles. It must have been their nap time though for 5 of them to sit still for 3 hours in a stroller, and he probably had to have mom along following on a bicycle to tend to unhappy little ones.
