Re: 11 wks, sudden fighting at breast, oversupply?
You have made a lot of progress! You've gotten rid of the shield, you've dealt with an oversupply problem, you've figured out how to nurse without the Boppy- I think you're doing really well, considering that your baby is just 11 weeks old!
Your baby's behavior is really, really normal. Frustrating, but normal. First, it sounds like you still occasionally have too much milk, like when you wake up in the morning. When a baby has to deal with a lot of milk and a fast flow, he's going to do all sorts of funny things, like pulling off the breast and screaming at you while he's waiting for the flow to slow down, burping and spitting up, clamping down on the nipple to try to control the flow, and acting like he can't decide whether or not he wants to nurse more. Babies have a high need to suck and sometimes their tummies get full before that need to suck has been fully satisfied, at which point the baby has to decide: stop nursing and miss out on the comforting feeling of nursing, or nurse more and risk ending up with an overfull tummy?
Evening fussiness is also textbook. It's probably got nothing to do with milk supply- if you can meet your baby's needs throughout the rest of the day, then you have enough milk in the evenings. It might have to do with the bottle. Baby spends all day bottle-feeding, and then in the evening he has to readjust to the breast, which delivers milk in a different way. Or it may have nothing to do with feeding at all. A lot of babies are evening fussers, sometimes so much so that their behavior is described as evenings-only colic, or the witching hour(s). If this is the case, try switching up your baby's sensory inputs when he gets fussy. Put him in the bath. Take him outside. Put him in the sling and go for a walk, or give him a ride in his stroller or swing. And of course, keep on offering the breast!
It sounds like you have a wonderful work set-up, where baby is accessible to you all day long. Correct? So if you feel that bottle-feeding is causing problems for you, maybe take a few more opportunities throughout the day to nurse. Nurse at lunch. Maybe once or twice more, if you can make that work with your work obligations.
Don't worry about the lengths of your baby's feedings. It is normal for young babies to spend a very long time on the breast- sometimes up to an hour- and to feed very frequently. A 60-90 minute interval between the beginning of one feeding and the beginning of the next is quite common.
