Ivy is 18 weeks old and sleeps from 6.30 to 6.30 😇 she never seems hungry every 3 hours in the day when I feed her, she has 5 bottles a day of between 4 and 6 ounces, I want to wait longer to feed her as feel like I am force feeding her half the time but how will she fit all her ounces in then before bed? If she went to every four hours she would only have four bottles a day and struggles to drink a six ounce bottle even in the mornings. She is only quite small so doesn’t have huge bottles
