My DD is 8 days old, and had a tongue tie that was affecting her feeding but that has now been fixed. She seems to be latching on a little better but with one breast she brings her self off and seems to be frustrated/hungry still as if she's not getting anything from it and the other breast still seems really sore and painful. I need to get a manual breast pump to encourage both breasts to produce but dont know which one is the best to get, right now im leaning more towards the Avent manual pump as it seems to have the best reviews but dont wanna spend nearly £40 for one that doesn't work, any recommendations???
