Hi R.-
I am a Mom to two boys - 2 1/2 yrs, & 6 months. My oldest was a little premature, & he slept in the room with us for several months. He was the same way, wanted to be rocked to sleep, then needed more rocking once he woke up. I received lots of advice from friends/family & was given several books to read by people who told me I was making it harder for myself by not letting him cry it out. Bottom line, I too opted for a "no cry" approach to sleeping. I was working Mon-Fri; son was kept @ home by grandmother. I gave him all the time & snuggling he wanted from me at night since I was gone so much during the day. He generally did well once I rocked him, & he's happy, thriving, and doing awesome today. He started sleeping through the night around 9 months, & only occasionally would wake up & need some snuggle time. It was also around 9 months that he began weaning. I don't know if your wife is nursing, but if so, this may have something to do with it. Also, babies have separation anxiety toward the 9mo mark, so the transition from your room may also have something to do with it.
All that said, here's what I would tell you:
1. Babies will sleep through the night - eventually! :-)
2. Follow your instinct, if it's not right for you to let your baby cry it out, don't.
3. Comparing your baby to others may make you crazy. Unless you observe serious developmental delays, (i.e. baby doesn't sit up & others do, etc.), let her go at her own pace. Consult your pediatrician if you have concerns.
4. All babies are different, & they have no idea what other babies their age are doing, so they may not do what "other babies do" as far as sleep patterns, eating, etc. My 6 month old started sleeping 6-7 hrs at a stretch, & he's also a breastfed baby who I again opted for the 'no cry' approach to sleeping.
5. Is your 7 mo old teething, on solids, etc? We've tried rice cereal, & we try it in the evening - having a full tummy may help w/sleep. Also, baths, stories, other night time routines help.
6. Last, I work night shift 2 days/week as an RN - baby has a little 'snuggle blanket' that I sleep with a night before I go to work - my scent on the snuggle item seems to help as well.
As far as "harm" in having baby sleep w/you; I dont' know any high school kids, or adults, who still sleep w/their parents. :-) Routines are important for babies to feel secure & safe, so it may take some time & reassurance to complete the transition.
Sorry for the long post - was kind of a hot button issue for me when everyone was telling me I was wrong for not letting my son cry. I don't necessarily think it's wrong to employ different methods to help babies get to sleep; however, I do think that bottom line, you have to do what you're comfortable with....good luck!
