By coincidence I have a bf baby he's 8 and a half months old and because today 2 of my bb holding older dc's left school early for dentist appointments I thought to myself I know I shall give this a go and see what happens.
Now the obvious differences are I know my dc's disabilities and I do know that keeping them out and about in town when its cold longer than absolutely needed can cause huge problems as can having to listen to aforementioned baby crying and we do not know that about the op but we do know because she has said that returning to the shopping centre or taking the bb holder out of the car again would have been an issue.
Anyway I took dc's to the dentist and parked in a bb parking space ( la space not private company ) as it would happen my dentist is 4 doors down from the transport management teams office that incorporate the parking ambassadors ( fancy name for traffic warden) so pretty much guaranteed I would have several pass the car,
I displayed a bb relating to a dc not myself after the dentist I returned to the car baby woke up as we walked out of the warm dentists so I put the dc in the car and after the slandered tug on my top from baby I sat in car and bf baby during the time I was there a group of 3 came out I called one over and directly asked if I was misusing the badge in any way by being parked in the bay at the end of my outing to feed the baby before I started my journey home.
The answer was no. Providing I was following the instructions on traffic signs that I was not leaving the bb holder in the car whilst I went shopping/ left the car and providing I was displaying the bb for one of the cars occupants and not one for a person who was absent then all was well.
I also asked if a bb holder returned to the car wishing to eat/ check map/ make phone call ect before leaving the bay would that be ok again the answer was this is fine. You are allowed to do everything a none blue badge holder is allowed to do before vacating a space in the allotted time for your stay to not allow a bb holder to do so would be against the law.
Apparently this is something they get asked lots due to people getting a bit weird about parking spaces.
Tomorrow I am in a different county I'm more than happy to try it again there just to see what happens.
