Moving to cows milk and being out and about - any advice?

[ELB1]

DD is 1 tomorrow and I think I should start thinking about moving to cows milk (she eats solids well now and has 3 formula drinks a day (am, pm and bedtime). AM and bedtime will be fine for cows milk, but if we are out and about in the day - does anyone have any tips for storing it in your bag? Is a cooler bag OK, or should I maybe try and keep to formula for this drink?

Any pros and cons?

Tbh I wouldn't even worry about keeping it in a chill bag in this weather unless you're out for more than say 4-5 hours before it'll be used. If you take it straight from the fridge into a sealed cup/bottle/beaker I reckon it'll be fine for a good 3-4 hours personally.

I'd just take beaker of water + a pot of snacks with you. They only need 12-16oz of milk at this age and some of this can be in food and cereal. If you are somewhere where you get get a fresh glass of milk thats great otherwise its too much bother imo.
