Feeding your baby when swaddled is okay but I would recommend removing the baby from being swaddled and then feeding them.
The baby will probably feed much better and you reduce the risk of the baby choking during feeding but according to doctors it's safe to feed the baby when you have them swaddled.
But in my own opinion and because I would not want to risk any problems with my baby I would unswaddle the baby when feeding them.
Then I would swaddle the baby back up after feeding.
But that is just me and what I would do but several people have said that they fed their baby when swaddled and they were and are okay.
So you can swaddle the baby when feeding them if you want too and it's considered safe.
