My 3 month old DD does not accept expressed milk from the bottle (given by my husband or someone else). She used to take milk from the bottle when she was 1-2 weeks old but I stopped to prevent nipple confusion. She seems to consider the bottle nipple as a foreign object and pushes it out with her tongue.
I sometimes need to keep her with her Dad for a few hours but now she has to come with me everywhere. Her Dad fed her with a syringe once and she gave him a very hard time so he will not babysit her anymore until she accepts the bottle!
