Hi Valentine,
I exclusively breastfed Ash for 6 months and then had to start introducing a bottle because of going back to work. I still did morning and evening breastfeeds for the next 3 months, then we swapped to just 2 breastfeed in the morning.
However, I don't think this was regualr enough for my body to maintain my supply and Ash started to cry and pull away. I made the decision to express morning and evening and freeze the milk. I only get about 1 oz, 1.5 if I@m lucky every 12 hours from both breasts, but that's enough for him to have 3 bottles of breastmilk per week. Like you, it's my compromise to enable him to have breastmilk for as long as possible. It's a pain having to express twice a day but I'm determined to do it for him.
Occasionally in the night I can get him to latch on and feed for a little while, so we still get our breastfeeds now and again,
So don't worry, it's not the end, it's just a new chapter. You've done amazingly well you should be very proud of yourself.
Keep expressing and storing your milk to keep your supply up, and I'm sure you'll be able to give her breastmilk for a long time to come, and you might also get some sneaky feeds now and again!
