Tasha we have just transitioned to a sleeping bag too. I felt I needed to bc he has just started to roll & he surprised me when I found him on his belly after a sleep. Don't shoot me but we didn't have a problem with transitioning... I think it actually helps bc he was kicking his blankets off & this way he always has something on his legs. I just have a really lightweight bag & he's just in a jumpy with no arms & legs. I put him in a jumpy with with arms, no legs when it's a bit cooler. I just did what you did (I think it was in another thread?), did a couple of sleeps during day in it, then that night put him in. Maybe give it another go, she might just need a bit longer to get used to it? Also my little guy was really tired when I put him in it the first few times, don't know if that helped or not. Good luck. ; )
