I would say ummmm NOW....she should be rolling over with in the next month or so and the sooner the better......
as for the snuggle time...as much as you love it break that habit NOW too.....she needs to get used to falling asleep on her own in her bed and not in your arms...
I have three boys and the only one I didnt follow my advice for was my last one ...man o man he just turned three and to get him to fall asleep on his own and in his own bed was a nightmare...he STILL wakes up at night looking for me (he shares his room with his 5 yr old brother)
so learn from my nightmare???
Break the habit now.....snuggle time is ok but put her down still awake...groggy but "aware" that she is in her bed and falling asleep on her own....
