My son is 6 months into treatment and achieved weight restoration about 6 weeks ago. His dietitian tried to prepare me for the stress and exhaustion of refeeding but even with the warnings, I wasn't prepared for it. Especially because we decided early on that I would be the primary feeder and the one to attend all of his sessions, which meant that I had my husband constantly second-guessing so much of what I was doing (his natural instinct to question everything is why we made the choice to do it this way and it was the right one, but it still drove me nuts!)
Now that we have moved into phase 2 of the process, I definitely am finding myself in a weird emotional space. I think it has a lot to do with handing over more and more autonomy to my child. I was so careful about everything involved in refeeding and even in the worst moments (hello, flying plate full of food thrown across the room!) I found comfort in knowing I was doing what I needed to do to heal my child. Now that he's getting back more control, I am often panicked about his choices and worried about it all falling apart again. And those feelings come out in odd moments all the time, mostly because I don't want to undermine his progress by freaking out on him if I think he needs another scoop of rice or something like that.
I will say a big help has been the parents I've met hanging around the office waiting for their kids to finish appointments or come back from a food exposure outing. We've created an informal sort of support group and I think it's a nice way to share notes and stressors. I also find a ton of support and ideas on the Around the Dinner Table forum:
https://www.feast-ed.org/around-the-dinner-table-forum/. Just a caveat with that group--a lot of people are in very high states of emotion, so make sure you aren't overwhelmed by reading something that could send you into a tailspin.
