breastfeeding coming to an end?

Katie • ...
My boy is 5 1/2 months and had just started solids as he was ready! He loves it, however I'm noticing my milk seems to have dropped! My periods returned today which I thinks down to him having food! He still breastfeeds between 7-10 times a day and has food twice a day after a breastfeed! I really don't want my breastfeeding journey to end! It has been one of the best experiences of motherhood!
Help!!
