Please share your experiences about getting a baby who slept on your chest/in your arms transition to sleeping in the crib.

1)At what age did you make the transition?

2) Did you start out with naps or bedtime?

3) Was the baby awake or asleep when you laid her in the crib while transitioning?

4) Did you attempt during all sleep times or was it only for one session initially and slowly worked towards all sessions?

5) If the baby resisted, did you keep trying throughout the session even if it meant that she missed sleep in the session or did you give up that session and tried again the next time? If it's the latter, how long did you try?

Some background:

I'm a FTM who is returning to work full time in a month. My 3 month old baby only naps in my arms. She sleeps in her crib at night, but has to be fully asleep before she is transferred to the crib.

I have tried the following to get her to nap in the crib but with no luck

Swaddling her

Dark room

White noise

Fleece crib sheets

Putting her to sleep as soon as she shows signs of tiredness

Maintaining room temperature similar to night

Each time, she wakes up in two minutes after being laid down to the crib.

Once I tried three consecutive nap sessions (rocking her to sleep, laying her down, picking her up when she wakes up, repeat)and she didn't nap for more than 20 mins altogether in the three sessions. She was so tired by the end of the third session and I felt terrible. This was a couple of weeks ago (she was 10 weeks old at the time).

These days, I take one nap session (around 4 pm) and attempt twice. If she resists, I give up and let her nap on me. So far, I haven't been able to get her nap even once. She does seem more comfortable when she wakes up though ( instead of crying as soon as she wakes up, she sucks on her hands for 10 mins trying to soothe herself before crying. I suppose that's an improvement?

At this point, I'm very worried about how her grandma will be able to care for her once I get back to work if she needs to be held to nap.

I would love to hear some successful transition stories. Help!
