DD napped well in her crib until about a month ago? She just turned 4 months and the crib has been hit or miss for at least a month. If the crib doesn't work, then I put her in the swing. For the last week, the crib doesn't work at all so I always end up transferring her to the swing anyway. I let her fuss/cry for up to half an hour before doing the transfer. Should I just cave and let her sleep in the swing from the start of the nap? She sleeps fine at night in the crib so I'm thinking maybe it's OK to nap in the swing? Or am I setting myself up for a problem down the line?
