Bottle feeding for the first time

Ra

My baby is 2.5 months old and the hubby and I have our first night out planned at the end of the month. We're going to a Garth Brooks concert for all you country fans out there in glow world. So we are going to try and give her a bottle tonight for the first time. Going to use a tommee tipee bottle. Any tips from experienced mamas? Hoping it goes smoothly 😆
