A Mare's udder will start developing around 30 days prior to foaling. Mares who have foaled before may have a small bag and even some fluid year round. Maiden mares and sometimes a few experienced mares can foal with no udder or milk, until during or after the foal is born.

Mares that have been on fescue hay or grass before foaling will not produce milk, your can get an antidote from the vet to bring in the milk, but you must have an alternate source of colostrum for the foal.
5. Changes in mares udder (milk bag) and teats.
Note how teats start pointing inward, and then change to pointing more straight down as mare's udder progresses. Also note some mares will foal with no change in udder size until after having foal.

Waxing: dried milk on end of teats
(very few Miniatures wax before foaling)

337 days: 1pm, foaled 11pm.
6. Changes in color and consistency of milk.
Milk should be easy to express from teats, changes can occur within hours or over a day or more.
If you find the thick sticky, yellow colored fluid, watch that mare! Foaling should occur soon!
Do not leave a mare unattended for more than 1 hour that is showing any of these stages of milk.
You can also buy a kit with test strips to test the milk, they measure the amount of calcium and/or PH level and use that to predict foaling. This can help if you are new to foaling and need reassurance on the color/consistency of the milk.
