Hi Heidi, all i can suggest is that you are right about your suspicions about the chocolate/tea or that maybe there is a hormonal element... it's common for babies to become fussy at the breast when AF returns but I guess she has returned for you by now? Other than that maybe your flow has reduced and he is frustrated.... caffeine is dehydrating... have you increased your water intake? Have you tried giving the ABA a call? They offer free advice that might be helpful... Good luck and congratulations for feeding your son so well for so long
