How to juggle expressing for bm top ups with feeds?

[Tier500]

I need to start topping up my 9 week old baby as her weight gain is slowing. Practically, how do I do this? Should I pump after every feed? And then when do I give her the top ups - small amounts after every feed or do I save them up and add in a bottle only feed? And when can I stop the pumping regime? I’m gutted that this is necessary and feel completely overwhelmed by the logistics.

Are the babies that "normally" gain 1 kg breastfed or bottle fed though?

All sounds fine to me.
Key - is baby pooing each day and numerous wees. And is putting on weight.
Averages are there for a reason, some babies put on lots fast, some slowly.

I'm a bf peer supporter so technically I'm not allowed to advise, but I would not be referring your baby on those figures.

Stick to your mummy gut instinct.
Go back to (a different) GP if you are still worried. A good HV can be as good as a GP, simply because they see hundreds, thousands of babies.
But in the absence of that support see a GP.

Feed feed feed. And cuddle!

Another miserable update from me - on Friday/Saturday she just stopped latching properly. It feels like her tongue tie has (unbelievably) reattached for the second time. I’ve had another miserable couple of days of trying to feed her and squeeze milk into her while she sucks half heartedly on my nipple. She fell asleep feeding at 10ish and was definitely getting milk then but stirred at 12 and 1 and I haven’t managed to get her to stimulate a let down so feeling absolutely terrified that somehow all my milk is completely gone. Texted lactation consultant last night and no reply yet. I’ve emailed my GP in the middle of the night asking for domperidone as a last ditch attempt. Covid makes it so hard to get any kind of help and I just feel so alone right now and that I’m failing my beautiful baby and also my toddler who can’t understand why I’m crying all the time.

Oh I'm so sorry it's so tough for you. Remember that breast milk doesn't make you a mother, your baby would also thrive on formula.
Don't beat yourself up

Hi OP
I have sent you a PM

Your milk does not disappear overnight. It is supply and demand.
Sadly it is possible for tongue tie to reattach.
Can you see a (different) lactation consultant, to ask for advice in person?

Or a bf counsellor, who can help you with your emotions as well as the technical side.

@Tier500 how are you doing?
