i am breastfeeding my 11 week old and started to try her with bottles of my expressed milk at 4/5 weeks old with no success - i have spent a fortune on different bottles and finally found a possible one - its Nuk. my partner gives her a bottle at nighttime feed but she often needs a top up from me to settle. also she is better with the bottle when sleepy and screams or refuses often. any advice on getting hr used to the bottle
