But the
problem with existing baby
sleeping bags is that you would need to buy a handful of different
bags for different seasons and ambient temperatures, which is expensive and can be confusing for first time parents....
However, the
problem that I found
with this is that when I poured thawed milk out of the
bag, it would always spill out through the adapter hole if I wasn't careful (and in my
sleep deprived state, I forgot... a lot).
