Need advise, baby and I have been ebf for one month & she will not nurse on both boobs longer then 6 mins, usually she'll go 25-30min each but when we get too about 5 mins she starts crying hard And won't latch or she will then seconds later start crying again. I tried too take notice to what might be the cause and I think it may be my nipples going soft. I don't know what too do, I don't want too pump & I have a shield but she won't eat with it. Need help ASAP
