i have just given birth to my 1st child this year and have been breastfeeding him since. I understand we lose our nutrients to our child through breastfeeding. at this moment I literally feel weak in my knees. I dont't know how to exactly describe this feeling but my family has history of anthritis. my mum has it at the onset of 40s. would like to take glucosamine supplements but worry it is not suitable for breastfeeding. any advise?
