How old are “babes in arms”?

[ReeseWitherfork]

“Babes in arms” go free… but what age is that up to?!

@ReeseWitherfork i have just booked my local theater and this is on their website:
Children aged 18 months and under are welcome, on purchase of a £5 Babes in Arms ticket and must share a seat with you

Oh that’s good to know thanks @HelloAllll

@mrsm43s DH will come too. Hopefully we can wangle it. I don’t want to miss out but I’m struggling to work out the logistics of leaving them (BF). I’m sure at 8 months they don’t need feeding that often… you’d think I’d remember having been there not that long ago with DS.

I think I’ll just book tickets for the three of us, and weigh up if DT will be more hassle to leave or take closer to the time. This thread has given me confidence that they would likely be classed as babes in arms if I need to take them.

Ones that can't walk. But dd walked at 9m but a regular place still let us in for that price as she was so young

For a theatre, if they are too young for their own seat and fit in your lap then they are a babe in arms. 18 months makes sense. You wouldn't book a seat for a six month old!

Without any context, I would have said 6 months - a small baby who still wants/needs to be held like a baby.

With context, it would have been less confusing for them to say 'lap infants' or something like that.

I would say under 1s. When they turn 1 they're no longer babies/ infants, but toddlers (even if not walking yet).

Although depending on context, it might mean a non-mobile baby.
