Hi everyone
Recently moved my almost 4mo baby boy to flow 2 tommee tippee bottles. Since around then he is really struggling to drink his whole bottles and has to have two sessions with each bottle which he didn’t before and still now it drinking as much as he did. He had covid just before this and went off his milk for a little bit then. Should I go back to the first flow tests or preserve? Has anyone else had this problem?
Also unsure if he is teething - can see teeth in his top gum but not his bottom?
