welcome to mamfa and gem. I'm in barnsley with a 5 yo ds and 2 yo dd.
Knickers - im a bf peer supporter. haven't much time right now, but.. tiktok's advice is spot on (as always re bf). give her loads of skin to skin - have a bath together, lay in bed together etc and let her have a comfort nuzzle. it may well work, relax and give it a chance. good luck
