My son is 6.5 months and only naps when held. I've tried putting him down every day for 2 weeks, but he either only stays asleep up to 15 minutes
or if I keep trying he gets overtired and throws a mini tantrum and isn't easy to calm once he's that tired. After trying today, he was so angry, but I finally got him to sleep 2 hours ON MY LAP. So he sleeps great in my arms, but not on his own. I've tried the swing and bouncer, he gets frustrated quickly. He does fall asleep in the car and stroller and that's fine, but I really want him to nap in his crib or pack n play. I've tried putting him down awake and fully asleep. I keep the room the same temp as bedtime, play the same white noise, and I have darkening shades. We won't do CIO method because he already shows way to much anger in just a few minutes in his crib. He is not emotionally right for that method and neither am I. I don't mind holding him, but I don't want him being a year old and still needing it. He sleeps great at night, just not naps.
