10 Month Old Won't Nurse Before Bed. Advice?

Hello, folks.

Within the last couple months, my wife has started a more "9-5" job, and only nurses our 10 month old daughter at the beginning of the day, and before bed. I'm a stay at home dad, and I give her a bottle mid morning, as well as mid afternoon. She eats finger foods and oatmeal for breakfast, finger foods for lunch, as well as whatever we are having and finger foods for dinner.

However, in the last week, maybe a bit longer, my daughter refuses to nurse during her typical pre-bedtime nursing session, and gets really upset if we try. However, she does typically take to a bottle.

My wife is pretty upset about this, as she has been nervous about her supply dwindling anyway (we have plenty frozen from before), as well as the connection she gets with our daughter at night.

Is there any advice anyone has for me? Is this natural weening? A nursing strike? Any of it would be fantastic!

Thanks!
