First, do NOT try to force her. My DS did the same thing around this age and I tried to force him - ended up with breast refusal, which was even harder to deal with.
they get very distracted and interested in the world around them at this age and have less time to feed. She may now be having much shorter feeds...? Just watch her output to see if she's getting enough. She may also be more interested in night feeds than day ones at this time.
You can try taking her to a quiet, darkened room to feed - that may work better for you.

all the best~~
