Here lately, dd hasn't been nursing well, I'm lucky if she nurses on one side. She cries, and sometimes latches on, and sometimes we have to try again 30 minutes to a hour later. Sometimes she will only latch on for 2 minutes and others she just smacks her lips. I'm afraid my supply will suffer and I don't know what's going on. She's been congested and gassy but that doesn't typically stop her from eating. Thoughts???
