Maybe try a sippy cup? My daughter does it every once in a while. Before we had a sippy cup I would mix the baby oatmeal (not rice) in with it and spoon feed it to her so she'd still have it in her system and get the nutrients.
I noticed like three - four days ago. She'll drink it before bed or in the morning but that's about it. When she's with the baby sitter she drinks it but with me she won't. @beebaby, when I try to give her milk she'll just move her head or hold it in her mouth and gargle it lmao I don't know what to do π
