Started my 10 wk old daughter on bottle of expressed milk for the last feed around 5 weeks. She took it no problem for about 5 days then has flatly refused ever since. Tried Avent, Tommy Tippee and orthodontic teats. Tried it when she is straving but ths is cruel and painful and have to give in eventually. Any more ideas? Going back to work at 6 months and would occasionally like to have break and leave her for a few hours but cannot at the moment.
