My two week old I’ve been breastfeeding and bottle feeding flitting between the two as found breastfeeding difficult. When I breastfeed she feeds for about ten minutes but then wants fed again within twenty minutes afterwards and this goes on for 7 hours or so continuously on the breast. Her nappies weren’t very wet and she screams with hunger. I gave her formula as my nipples were bleeding and cracked and she was content for the first time. I then decided to formula feed but do still want to breastfeed. She’s having a tongue tie corrected today so I want to try again. But I also have a 16 month old so I can’t spend hours on end breastfeeding as he’s demanding too and I don’t have time. Any advice??
