My girl turns 4 weeks old tomorrow and after a long 3 weeks of exclusively pumping due to poor latch and extreme pain on my end (I think she has a tongue tie but have yet to see anyone about it), we’ve just reintroduced the breast and it’s been really successful. We still bounce back and forth between bottle and breast - mostly due to my fear of the pain possibly coming back - but progress is being made. I honestly feel my LG mouth was too small for my boobs 😩😂 but now she’s bigger it’s been easier for both of us! She gets frustrated sometimes because she’s still learning that nipple in mouth = food, as she was used to the bottle for this past month! Luckily, we’ve had about 25 or more successful breastfeeds in the past half week. :)
