Hello,
I am pregnant at the moment with baby No 2 and we went today to view in real life an out n' about double buggy.
We loved everything apart from the waist straps...
We tried to put our 22 month old DD in it and put straps on and they just fitted her around her waist at the biggest setting and without her coat on... We wouldn't be able to put the straps with her coat on!
The shoulder straps were quite spacious though and seem to have some room for growing.
Does anybody else had this issue with the waist straps?
We would like to use the buggy for at least 1.5 years ahead and our DD is not even 2yrs yet... 
Do you use it without the harness with older toddlers?
Please tell me that we missed something as it's otherwise a lovely buggy!
