Airport Security & Formula

My husband and I are flying with our little one in August when he will be about 6.5 months old. Does anyone know how much powder formula is allowable through security? We are only taking carry ons and our trip will be about 10 days long. So I’m trying to figure out how much I can get away with taking in our carry ons (since it’s all a bit more expensive to buy where we’re going). Can anyone share their experience and how much they were able to carry through TSA? The whole security process with a baby already freaks me out a bit so that’s why I’m particularly nervous about this 😬
