Baby bottle

I’m on my first rewatch & I noticed that Kat is drinking out of a Tommee tippee baby bottle in one scene, then out of other baby bottles several more times. Yesterday I noticed Nettie filling a baby bottle with sweet tea & giving it back to whoever in the back seat, I assumed Kat again 🙃 This was after stating that Kat is 3 years old at the beginning. she’s old enough for a spray tan but not too old for a baby bottle 😅 make it make sense.
