Not sure if I want help, a rant or a magic answer 
DD was breast fed, took a dummy, occasional bottle, no problem.
DS is 3 months old. Dummy refuser, bought and tried loads. I've left him 3x and he took a bottle of formula, not great but drank it eventually.
However while out for a meal on Saturday DH had to ring me to come home as he wouldn't take a bottle or stop screaming.
All week I've tried expressed breast milk, different formulas, me feeding him, DH feeding him. We have the Avent natural bottles with all different flow teats, and I've bought a mimijumi bottle and doidy cup. No luck.
Today I was determined to crack it and went on nursing strike. DS still refused the bottle after 8 hours without milk so I gave in and fed him myself.
The next few months are looking very bleak if I can't attend one meal, cinema trip, gym class.
Help please mumnetters.
