Welcome to my world..my 4 month old took a bottle and then refused it at 3 months. We've tried everything! My parent's will drive him to my work when I go back in a few weeks. Some babies just won't take a bottle.
1. Try different nipples.
2. Try different temps of milk
3. Rule out any medical reason
4. Wrap baby in your clothes when nursing.
5, Spoon feed (tiny amounts) just to get it in her mouth.
It is not necessarily true that they will eat when hungry! Once they are totally worked up, they won't be able to suck and swallow.
Talk to your work...you aren't the first mama to deal with this. Are you close enough to the daycare to go feed your baby/nurse her? In the state of californi your employer must make reasonable accomodations for you to pump/nurse your baby.
Is there a family member that can drive the baby to your work to nurse or for you to feed her or can you switch daycares to be closer?
It may be that you just need a bit of time. My friend went through this for 6 weeks upon returning to work and then her baby just decided to take a bottle.
Your munchkin may just do it or not...
Good luck! I am so sorry! This sucks! It keeps me awake at night knowing I have to deal with this when I go back and knowing that my son is upset when I am not there. We are very hands on parents and this just makes me miserable!
Take care,
Keeping my fingers crossed for you!
