@Amy see that’s the problem, she will be screaming for the bottle 2 hours after her last feed and snatches to grab it when I put the teat near her mouth and guzzles straight away, but sometimes drains the bottle and others stops after 2ozs
Yes, that's normal. They won't usually drink the exact same amount every time.
Yes normal. My HV says "would you eat a full English for breakfast at 8am every day or do you sometimes only want a bowl of cereal at 10?" Their appetite ebbs and flows just like ours
Maybe try longer stretches if it doesn’t seem like she overly wants a lot maybe try 4 hours c
