My LO is 6 months and still mostly naps on us. We sleep trained a few weeks ago and she got nights straightened out pretty fast but getting her to nap in the crib is still a disaster unless we get the timing precisely right (like, within 2 minutes of a magical, mythical sweet spot of no too tired not under tired). I think we've decided it's too stressful on all of us and are going to keep the naps on us or in the carrier for now.

Any other suckers that let their baby nap on them past the newborn stage?
