I got a little lazy over the long weekend (4 days for me) and I latched/pumped less often. dragged the intervals to 5-6 hours (used to be 4). I could pump about 200ml (both boobs) every session before. now I can only pump between 70-150ml per session! left boob also feels bruised at the bottom. help! should I intro formula? baby is 7-months old and on full bm so far.

The decision to introduce formula is a really personal choice. Bm production is really a matter of demand and supply, it seems like because you lowered your pumping frequency, it's sending a signal to your body that less milk is required, hence, the decreased output. If you decide to continue on exclusively breastfeeding, you can try the various ways to increase your bm supply by power pumping or taking some galactagogues like overnight oats or fenugreeks. http://kellymom.com/hot-topics/pumping_decrease/ Jiayou and well done for exclusively breastfeeding for the past 7 months!
