Trying formula after 13 months

Maggi

After 13 months of exclusively pumping, I’m ditching the pump. I have a trip next week with my little one and I don’t feel like flying with a bunch of frozen breastmilk, so I was gonna try formula. I got questions...

Is 3 days before the trip too short of notice to try to find one that works?

At 13 months old, is it okay for him to have formula? Are there specific kinds that cater to this age?
