Many times now when I have the baby in a sling, the bus driver has driven off before I have any chance of sitting down. Usually there are free seats, so I'm not taking time even by waiting for someone to get up. One yesterday started driving away as I touched the card on the reader, not for the first time. It isn't the same driver, nor even the same bus; quite a few will wait but an equal number don't. AIBU when I shout to ask them to wait as I have a baby in a sling? Should I assume they'll take off and ask them to wait for me to sit before I touch the card? It feels so dangerous for the baby when the bus is rocking around and other passengers wobbling about; is it just me that worries because I have tendonitis and I can't rely as much on holding on, so I should be explaining that to the driver instead of assuming they'll realise a baby is vulnerable? What do other people do?
