Help my poor boobs!!!!

Laura

My baby is 9 days old and his hunger had increased lately.. I'm currently breastfeeding but my nipples have been so sore and painful... he has an extremely strong jaw and I feel like he's sucking my soul out of me everytime.. what can I apply to my boobs? I have only tried the lansinoh cream and to be honest I don't see a difference... please help 😣
