Just to add to a lovely comment from Jean Ridler, with a follow-up comment from Terese Pitman:

Hi,
One way I have of addressing this, which I thought of forty years ago when there was a temporary fad of recommending only 3 feeds a day for babies, is this.
I'd ask Mums how often the adults they knew took food or liquid by mouth, either in the workplace or at home.  This was usually at least six times a day, and more if the adults also got up to the refrigerator in the night.  (Whenever I've stayed overnight with a bunch of adutlt, the refirigerator door was opening and closing all night, usually just after the toilet had flushed.)
An adult food intake might be something like this (with variations):
1. Coffee/tea on waking.
2. Toast or cereal before heading to work
3. Midmorning break (round the coffee machine /water cooler or at the desk)
4. Lunch
5. Mid-afternoon drink (adults), or snack (school-age kids)
6. Drink and something to nibble with mates after work
7. Evening meal
8. Hot drink before bedtime
9. Possible drink in the night?
Then I'd suggest that babies would surely need to feed at least as often, perhaps more. (Talking about supply/demand could then follow.)
Cheers
Virginia
