Teething infant fussy?

I have been on international travel for a month with a 7month old baby whose 1st tooth appeared about a week ago. Before this travel, I would pump-feed a lot and semi-solids 3 times a day. Because of the travel, breastfeeding became more convenient.
However for the past few days she has been refusing breast-milk-in-bottle or semi-solids. All she wants is the breast. The fear is she starts day-care as soon as we get back home and I am scared she will be a mess
Wondering if teething is the culprit or is it meeting strangers and being on travel.
Anyone else face this?

You can easily throw a baby off her schedule, but I think the main culprit is the closeness she feels while breast feeding. Try putting the bottle very close to your naked breast and see if she will take it that way.

If the baby gets hungry enough she will eat from a bottle if she realizes what it is, but she will be very cranky until then.
