5.5month-old prefers bottle to breast - worried about supply

[mariamenendez]

My dd is 5.5months old and barely feeds for longer than 5mins on each breast now. It feels as though my supply is getting lower and lower, so I have started to give her a 4oz top-up of EBM or formula at 7pm. Despite showing barely any interest in breastfeeding at this time she lunges at the bottle with both hands and downs it as if she's starving!
I breastfeed her before her bath and give her a bottle after so she doesnt associate them.
Is she just lazy? She also has had a bottle of formula every night at 11ish since 6wks due to PND, but has never spurned my breast in favour of the bottle til now.
She also throws up after most breastfeeds now, which she didnt used to do.
her weight and poos are fine.
Should i stop giving her the top-up? she sleeps through from 11 til 6.30 now so don't want to risk her waking from hunger.
i want to BLW so wanted to maintain milk supply.
am i worrying about nothing?

Why not express your breast milk and feed it through the bottle?

Regular expressing will aid and increase supply, replacing breastfeeding with formula will decrease it. At your stage, your breasts make milk when it's needed and if not needed, the supply goes down.

Re weaning, breastmilk can be frozen so you can use it for making baby rice/porridge, etc. You can pour it in an ice cube tray, then when frozen store the cubes in a freezer bag. They last six months in freezer.

If you practise, you can hand express easily, no need to buy a pump. If interested, download the brochure below for storage and hand expressing info.
