i am a new mom to a 3 month old baby girl. she sleeps through the night in her crib since about 9 weeks of age (with an occasional bad night here and there). ((at bedtime, after her bedtime bottle-i nurse all day long but we give her a bottle of breastmilk at bedtime-i rock her then hold her for 45 minutes to an hour, then put her in her crib.)) but we are having trouble at naptime. she usually takes a short nap in the morning in between her 1st and 2nd feedings; i hold her since it's a short nap. then after her lunchtime feeding, i rock her to sleep, then hold her for about an hour to make sure she's good and asleep-which i know i need to shorten the amount of time i hold her too, then i put her in her crib. it never fails... she'll sleep for maybe 30 minutes, then wake up crying. i know she's ok.. she's been fed, changed, etc. she just wants to be held. last week we started letting her cry it out in her crib. she cries off and on for at least 40ish minutes before going back to sleep (if she even goes back to sleep) and doesn't stay asleep very long. the last 2 days, we've picked her up after 20 or 30 minutes (we have a mobi video monitor so we can watch to make sure she's not hurt.) it's extremely difficult to listen to her cry and it doesn't seem to be working. while i am a stay at home mom, i can't continue to hold her for hours while she naps during the day. please help!! any suggestions are appreciated.
((also, the only reason we started the 'cry it out' method now-at 3 months-was b/c i felt like if we waited any longer, the problem would only get worse))
