When your LOs started pulling up in their crib, did that mess up their sleep? DD has always been a good sleeper and was able to fall asleep on her own when I put her in the crib drowsy but awake. But once she hit 9 months and started pulling up she would not stay down! I now have to resort back to rocking her to FULLY asleep before putting her down for naps and night time. If she's not asleep, right when her head touches the crib, she will roll over and pull herself up and cry and cry until I get her. It is exhausting! Did your LOs have trouble falling asleep on their own when they started pulling up?
