Breastfeeding 3rd child, there was query over this one having 'posterior tongue tie' when she had difficulty latching on, I had very sore nipples etc. They didnt operate as things got better. Now she is 3 weeks, feeding improved but I can hear her gulping air when she sucks - after 5 mins she is so windy she pulls off, then spend ages winding her, only for her to do it again..then finally so tired she falls asleep only to wake up hungry after an hour or two & whole cycle carries on.........HELP!!!
