Congrats on your baby
How are the feeds going with the shields now?
Who have you spoken to about your feeding issues?
Sometimes, they can work in the long term, if you've tried everything else and the feeding works like this. At worst, they're a nuisance
the only risk to you guys is if there's some other issue that this is masking, and continuing with the shields means the real problem is not addressed, and this ends in early weaning.
At this point, though, it's still really early days. So you have time to sort this out.
