Did your baby like your sling/carrier/wrap immediately or did it take time?

My 9 week old LO wants to be held all the time, so carrying her in my sling is the best option for my sanity. However, it’s been a few days and she still fusses and cries when I put her in it initially. After some time she falls asleep and sleeps peacefully, then wakes up crying. So I have to instantly take her out of it.

I’m not sure if I’m doing something wrong, or if it’s this sling she doesn’t like or if it’s just something that takes time.

The one I’m using is a Moby Fit. I’d love to hear your experiences...
