catbag pretty much the same yes. I was worried it would not fit around my tummy, but it does, so figure it will do fine when I have had the baby. I had a breast friend pillow with DD2 but gave it away when a pal had an EMCS. She asked if I wanted it back, but I said no, as we did not think we would have any more babies, so she passed it on. It was very hard, more like a shelf, and the belt was a pain. I am more confident this time, and know what a section will feel like, so think this will be fine, and can also be used for baby to sit up etc.
stunt I think if a mum has been tandem feeding throughout it is a bit different, as a toddler feeds differently, and the body automatically produces the right kind of milk according to who is suckling. Perhaps a post on breastfeeding or pregnancy forum may get you some answers?
