Bottles for over one

Hi guys, My little one has turned one a few weeks back and would like to change his milk bottle from the small Tommee Tippee to something more age appropriate in regards to his development. Any suggestions please as the options are endless. He currently drinks his water using the Munchkin click lock sippy which works perfectly but looking to update his milk bottles asap. Drinks cow full fat milk if that makes any difference. Thank you ☺️
