Legally yes. But I wouldn't unless an absolute emergency as if the taxi crashes, then there's zero protection.
Yeah you can!
My 3yo sits on the seat with a belt on but the strap that goes across his chest I stick behind him then give him my phone to keep him still x
@Emily I do the same, but l put that belt under her armpit.
Yes you can, occasionally I have to do it as I don’t drive x
Yes you can on your lap or separate seat with seatbelt
