DD was still feeding to sleep during the day & at night, by the end of the PG she was only feeding to sleep at night (& whenever she woke up). There were times when it was more sensitive than others but not overly painful IYKWIM
The hardest thing was tandem feeding because DD would get frustrated that she had to wait for DS to feed before she could feed. She ended up finding a dummy in the toy box when DS was around 2 months old & transitioned to going to sleep with that instead which really surprised me because she'd never taken a dummy before.
