Having a BFing crisis today, my 8 mo is teething and can't suck long enough for me to let down. He is biting really hard. He has missed the last 2 feeds so have just given formula which he drank down no problem. Wondering if now is the time to give up BF? Anyone got any advice? I have tried giving teething rings, bonjela and calpol before feeds but it has made no difference.
