I put my baby in her crib tonight for the first time !

So nervous !!! She's 3 and half months. She was sleeping in her swing since month old or so due to reflux . She has been sleeping through the night on lowest setting .. we bought a Merlin sleep suit and decided to try our luck. We did our normal routine and I put her down, roused her as I put her in the sleep suit .. she had her eyes open when I zipped up the suit.. she didn't need her soother. She startled a bit ... then turned her head and fell asleep.
