If you try to force her to eat, she will only become MORE resistant and start to dread feeding times. NEVER force feed a baby.
My suggestions - You replace on breastfeeding with one solid food meal. If she isn't hungry, she won't eat. Usually the easiest one to replace is the mid-morning breastfeeding session (10:00 ish)
she's also a little young for 2 meals a day. One meal a day at this point is sufficient.
Trying to feed her at 5:30pm is going to be tough, since most babies start their evening fussies at about that time. She may simply be tired and a tired baby won't eat solids either.
So, to sum up. Don't force feed her. Feed her mid-morning, when there's been at least 1-1.5 hrs (or more) since she's last eaten. She'll likely do better for you.
