Newborn babies need to be held pretty much all the time. It is normal. Besides using a sling etc, right after nursing is also a great time to hand baby off for a nice bonding, cuddle sesson with baby's other parent or grandparent or whoever is there to help you while you take a nap or a shower. Sometimes you can hold a baby long enough after nursing, to get baby into a deeper sleep and then put baby down (rather than putting baby down right after nursing.) Or hold baby until baby nuzzles for a top off, top baby off AT THE BREAST and then baby may be in a deeper sleep and may allow themselves to be laid down. Maybe. But a baby not being willing to lay down in a crib and sleep is not in any way an indicator a baby cannot get enough at the breast. This is just normal newborn behavior.
You understandably have concerns because you milk dried up early on with your oldest. Obviosuly I have no idea what happened there. But I do know that nursing very very frequently and avoiding/very strictly limiting bottles and pacifiers, especially in the first 2 months or so, is the single most important thing any mom can do to ensure great milk supply.
Thank you so much for all the great advice! I really appreciate it. :thumbsup
