At this point, I wouldn't worry at all about syringe feeding. How's her pooping? Is she doing okay getting rid of the syringe food . . . or has she stopped that too?
If she's NOT pooping, I'd definitely say NO solid foods yet. . . and recommend you keep her on the syringe food until she does (w/a lot of water in the mix).
Both my girls got syringe fed after their spays . . .Shirley for quite some time. She was tub trained and had wouldn't poop till I could soak her again....which the vet said should have been two weeks. It played such havack w/her blood chem though, that he relented after only a few days.
If Irish IS pooping okay, you might try handfeeding some of her favorites during the syringe feeding session. Start w/just a little to ease her back onto solids.
Or another good trick it to cut her greens in nice long strips than open her mouth and stick the first one in till she startes eating it. She may try to spit it out too but keep working at it . . . cause once you get her eating the first one, you can slip another one in while her mouth is open to chew. The 2nd piece will get pulled in while she's finishing the first and, unless she's REALLY, REALLY against the idea, she'll pretty much keep eating as long as there's something in her mouth to swallow. Again though....ease her back on to the solids slowly.
Also, and you're probably already doing this . . . even though she's still syringe feeding, keep food and water in her recovery area at all times. Romeo surprised the heck out of my by eating on her own within the first 4 or 5 days. It took weeks before I came home to find Shirley had stuck her nose in the food.
Hope this helps. Keep us posted.
