Good on you for persisting through your challenges. Sounds like you and your bubba are doing great. I can't help you with attachment advice. I will however say that my DD has to be the worlds slowest feeder lol. At 10 weeks some feeds were 2 hours long. She is 4 months now and her feeds are shorter. At 10 weeks I was advised to feed bub for however long she wanted, and to follow her lead. Give the ABA a call, I am sure you'll get some great advice especially with attachment. HTH
