You should feel pretty happy for BF as long and as well as you have. My LO needed a bottle to supplement at 9 wks - her feeds were getting closer and closer, and she was feeding for 45mins at a time. Gave her a bottle, and within 24 hours she absolutely screamed teh house down when I tried to BF her, and flat out refused to feed. Note also that after the bottle was the first time in several weeks that she lasted 3 hours between feeds, night included.
She has since then been only formula fed, and is thrilled. And I didn't even have to pump, I just didn't have good milk. But 10 weeks later I am still really sad that it didn't last longer.....
We were also co-sleeping, by choice. About 3-4 weeks ago, DH was on night shift, and I noticed that she suddenly did not wake AT ALL in the night. So now she is sleeping in her cot in her room.....and is thrilled (most of the time). But I am left sad again
.
Our little one is VERY independant, 19 weeks and trying to control her own bottle. She is not clingy to me at all.
Sadly, she is teething at the moment, and I am enjoying it, as she is cuddlier and clingier than she has ever been...I shouldn't feel that way, but I am enjoying the extra cuddles whilst she will lay still enough to have them.....
She is just WAY too spirited.
I know how you feel , and envy you for how long you have been able to enjoy your BFing.
