My boy is 8.5 months. He won't drink from anything except me. He went through a short phase of accepting a bedtime bottle from me and my partner and even had a couple when we were out and about on odd occasions but that has stopped. He eats fine but won't drink water or diluted juice from any kind of cup I have tried (tried straws, 360 cup, free flow beaker etc). He stayed overnight at my mums recently and had nothing to drink from 4pm - 10am. I'm freaking out and I keep trying to push bottles as I'll be going back to work soon and it's getting desperate. Please if anyone can offer help or advise?
