Silly question alert... So I'm out with sprog and I need the loo. How?

[Sarahjct]

About to be a first time mum here and instead of fretting about the impending ordeal I'm about to go through, I thought I'd contemplate silly stuff instead.

Supposing I take LO out to the shops - not out of the realms of possibility as I'll be kicking around the house all day. I'm in the shopping centre and I need a wee. How do I go about it?

My travel system is the size of a tank so wouldn't fit in a cubicle, disabled loos all seem to have swipe card locks to stop people like me using them (). Do I take LO in with me and do it one-handed, do I leave the door open and use humungus buggy to block me from view? Or do I leave buggy and child outside to be nicked?

This stuff keeps me up at night...

Deffo go on scouting missions now so you know whether all the big loos are. This is also a reason not to get a big pram, but something small and easy to squeeze into cubicles! Sometimes there is a larger cubicle on the end of a row that is just big enough, the other option is disabled.
On a related note, I had dreadful "performance anxiety" in a cramped cubicle with DD the other day. I think it was the first time that she really felt old enough to be watching what was going on. I mentioned it to DH, who told me that the last time it happened to him, he turned the pram around, but that she watched him anyway in the mirror.
