S.T.
I have a 20 month old son, and we're having similar issues, except that we cosleep already by choice, so I'm not sure why he's waking up so much.
But my reason for writing is to clarify something another poster wrote..
Co-sleeping doesn't work for every family, of course, and I'm not suggesting you take that approach. But it does not raise the risk of SIDS as she stated. There is a lot of fear based false info out there about this. The only parents who should not sleep with their babies are those with sleep apnea or morbid obesity, or those with a drug or alcohol problem. (This includes not sleeping with a baby anywhere, ie a couch .. Not just in bed). There have been many studies that have shown that babies crave safety and security, (no brainer), and they feel safest near us. When your hubby brings your DD in and she sleeps soundly, doesn't that make sense? Maybe you could put her crib next to your bed on his side? That way he can hush her or take her out of her crib if she gets upset?
Anyway, I just mostly wanted to say that SIDS isn't connected to cosleeping, and newborns thrive in a sleeping situation with healthy parents.
SIDS has been linked in some studies (where the victims were healthy children and healthy parents) to certain chemicals and flame retardants in kiddos pajamas and mattresses. The pjs cause sweating, the sweat mingles with the chemicals and creates a type of gas that has the same attributes as nerve gas.
