This Momma needs HELP!

Has anyone stopped nursing for 4 days and nursed one more time on day 5,or similar? Babe is teething and the only way I know to soothe is to breastfeed and let him drift off to sleep. I don't know if this will ruin what little progress we've made this far.

Ps. This has been super emotional for me too, so I feel conflicted. I want to one last time but also know I've made progress this far. :/

Any words will help. Thanks!!

UPDATE: I was strong enough to not give in and nurse him. Thanks for all the feedback!
