Boob refusal!!

[Tagz269]

Please help!!
My dd2 is refusing my right boob!!! Every afternoon/evening she always refuse ms it and would happily take my left one! I've tried rocking her to soothe her as she is crying her eyes out/tried the rugby ball/started on the other and swapped soon after but she just knows!!!!! It's not getting to the point where it's engorged as she takes it in the morning no problem... This boob doesn't produce as much milk and I've always thought that from the beginning but I don't want this to carry on!!
Help

All my dcs have had boob preference (slower let down and lower supply). I feed before and after naps and have more success in getting dd to feed from that side when drowsey ie. before naps/bed. Have also had limited success with walking around/rocking with dd latched on to keep her on there a bit longer during fussy periods.

Perfectly fine to only feed from one boob though for some of the day though.
