Re: Can't hand express after nursing - low supply?
Not being able to hand express does not indicate low supply, since hand-expression is a learned skill, and not something that everyone can do effectively at all times. The best gauge of supply is diaper output: good output = good input. What may have happened is that your supply has regulated. Most moms start out making more milk than their babies need- it's nature's way of making 110% sure that the baby gets fed. But making extra milk is a waste of your body's energy and also puts you at risk for things like plugged ducts and mastitis, so eventually your body uses the amount of milk left in the breast after nursing to figure out how much the baby actually needs, and down-regulates supply to more exactly match what the baby takes.
That being said, just keep an eye on weight gain. If you see several consecutive weeks with no gain, it may be time to check things out with the pediatrician. But remember that growth isn't always constant in all dimensions: some weeks a baby puts her calories equally into height and weight. Other weeks growth pauses in one dimension as calories are allocated to growing in another dimension. And once your baby starts to become mobile, it's very normal for weight gain to slow way down or even cease as calories that used to get packed on as fat get burned up in motion, instead.
