Lol This is hilarious - I've not heard of it this way before - but I have an accident colt at our rescue who's a gypsy vanner/shetland pony cross xD The mom was a Shetland - he was as big as her at 6 months old!!
Where there is a will there is a way, I have a TB mare that has pasture bred with my Icelandic stallion she is 16 hands he is just over 13, the smaller guys seem to be more endowed then the bigger guys. If the milk isn't clear anymore what color is it. If it's more whitish and has little white globes floating in it your mare is close to foaling. You can taste it and if it's sweet she's close if it's salty or bland it's not emminate but still close.
