I have 5 week old twin boys. I am tandem breastfeeding and we use formula to supplement. I would say at the most they get 5 oz a day of formula. The issue is they are hungry almost every hour. Sometimes they will go 2-3 hours but usual its ever hour. They are both gaining weight which i am very happy about but I just dont understand. Sometimes they feed on me for 30 -45 mins and then just cry bc they are still hungry. They latch my breasts get softer so i k ow they eat but even then when we supplement with formula...an hour later they are hungry. Anyone else experience this...I juat get so frustrated and if it keeps up like this i will have to stop breastfeeding since I will be going back to work. I dont even get time to pump since they are constantly at my breast. Any advice or stories would help. Thank you.
