wanted to add this about the ducts...

try to get your baby to drain the duct by pointing their chin to wherever the blockage is. this can mean a bit of serpent-type winding around your side.

my last one way on the left outer side so i had his body round my side and held him sideways in football, if that makes sense. if you have to lay them over the top then so be it. they know what to do. you might need someone to help.
