Should I up the ounces?

[Samr85]

My 9 week old Is taking a full 5 ounces each feed n was having 6 bottles in 24 hours but has recently started sleeping through the night having her last feed at 7.30pm n not waking till 7am for the next so should I now up her ounces to make up for the missed night feed?

if she is draining the bottles then add an extra ounce to each one

^^this.

Thank for your advice I just wasn't sure as health visitor last week said 5 ounces was a lot for an 8 week old?! She was having the 6 bottles then though.
