I had a 07 ch baby that was similar to this one. She had to be force fed (like you said getting the rat pink all the way down) 3 times. From there she was assisted (placing the prey in this case pink rats to fuzzy rats in her mouth and her swallowing on her own) at least another 3-5 times before she began constricting the already dead prey item once it was in her mouth. After she was assisted 3 times and she constricted 3 times the prekilled prey I placed a live rat fuzzy in her mouth and she constricted it on her own then ate it. Once she constricted and killed the prey item on her own she seemed to get it and begain eating (striking, constricting and swallowing) any prey item I presented to her. She is now pushing 2000grams and is one of my favorite balls. Her name is Pee Wee.
I never skipped a week of feeding with Pee Wee because she seemed to respond so well week after week even with forcing and assisting. She was so small I never wanted her to take a step backwards.
Good luck I hope my experience helps and your baby thrives!
