Re: Is my supply dropping/can't always feel let down...why won't my baby sleep???
Increased night waking is normal. Many babies wake more at night when they begin to teeth, or as they master new developmental milestones. As long as diaper output remains normal, the waking should not be taken as an indicator of low supply. Now is a great time to start making some changes in your baby's sleep routine- I suggest taking a look at Elizabeth Pantley's book The No-Cry Sleep Solution for gentle ways to encourage longer and more independent sleep.
Once you've been nursing for a while, it's normal to no longer feel "full." Most moms start out making too much milk, which is nature's way of ensuring that the baby gets fed while she masters the art of breastfeeding. But making extra milk is a waste of energy and puts you at risk for plugged ducts and mastitis, so after a while the body adjusts supply so that it meets demand very precisely, without a lot of extra milk lying around to give you that full feeling. When this adjustment occurs, sensations of letdown may diminish or vanish.
The fact that you recently got your period back may be contributing to some of the increased night-waking and also the decreased fullness. Many moms notice distinct dips in supply around their periods. However, as long as diaper output remains normal, your supply is okay. It may have dipped, causing the baby to nurse more often, but it isn't inadequate.
My only concern would be the IUD. Some moms find that their milk supplies really take a hit when they use hormonal contraception, so if you chose a Mirena IUD, that could be negatively impacting your supply. But again- count diapers. If they are okay, your supply is okay too.
