Sudden regain in interest in Breastfeeding!

Cynthia

Okay so my LO was born with mild jaundice so she was put on formula right at birth but I continued to still have her drink breastmilk & once the jaundice was gone we just continued on both up until she was almost 4 months bc she didn't seem to want the breastmilk anymore so we stopped, well now she is 8 months & has started to look for my boob again, she will latch for about 10 seconds & stop & just bite down & tug & pull my nipple. The whole time we stopped on breastfeeding I still produced milk (which honestly I'm surprised lol) but I'm wondering if anyone else has had this happen? Is it normal for her to want breastmilk out of the blue? & is it still safe for her to drink?
