Napping in my arms

Amanda • 33yo married mama of 3 girls & 1 boy!! Audree-15, Ayva-12, Marleigh- went home to Jesus after 11 days (2/3/18-2/14/18) and Corbyn- 4 months old 💖💖💜💙

My LO will be 4 months next week and has been wanting to nap in my arms only ..and I can’t put him down bc he wakes up!! He normally would only take 1 nap in my arms (since he naps much longer) and sleep in his crib/pack n play for the others ..but now won’t fall asleep and cries until I pick him up to rock him. And he wants nothing to do with his pacifier unless I hold him 🤷🏼‍♀️🤦🏼‍♀️ he’s fine at night though. Is this a bad habit and should I let him cry it out!? I’m just a sucker when I see his tears.
