Hugs hun, it must be so hard especially with a 3 yr old running you ragged as well!
One of the things The Sleepstore articles said that really resonated with me is that you have to be consistent with whatever you choose - if you're strict about self settling all day then feed them to sleep once you're back at square one. I just went to look up the article that said that and actually there's a
case study that's very similar to your situation (feeding a 7 month old to sleep) so you might want to look that up.
Good luck!
