It seems our little one hates her bassinet, so I'm looking into alternatives. If you've used these products, what did you think?
What qualities are most important or limited?
If your bed is already crowded, the cosleeper will add some space. But if the room is small, the nest will take up less room overall.
Is your babe "leaky"? The cosleeper can prevent pee/poo blowouts from forcing a mid-night family bed overhaul. The nest sits on the big bed so leaks go right through. But it's easier to clean the nest in the event of small leaks (cosleeper sheets are a pain to remove/replace).
Is your bed a standard height? There are adaptors, but the cosleeper works best with standard frames. The nest can go on any bed (also good for travel).
The co-sleeper will last longer (can hold a bigger kiddo, can convert to playpen, can hold laundry/diaper change supplies). But if you plan on straight up bed sharing down the road the nest may be all you need. And the nest is less expensive.
Depending on why your babe hates the bassinet, she may hate the cosleeper and/or nest. Both limit body to body snuggles/cuddles (the cosleeper has a "wall" dividing the babe's sleep surface from the adult bed, the nest has walls too). And both will require you to reposition or even lift the babe for nursing. The nest will give a more "snug" feeling while the cosleeper offers more space... is the bassinet too small or too big (in terms of her preference)?
You might consider renting a hammock or checking out an amby bed if she seems to sleep better with movement or a more upright position. Or sidecar a crib (if you have one) before buying a cosleeper. Or try straight bed sharing before investing in a nest.
