My 7 month little one is learning to crawl and pull up. She has been pulling up on her crib and trying to reach and falling and bumping her head on the crib. It even left a bruise. Is this normal? I’m always so anxious going to bed, and afraid she will wake up in the middle of the night and fall and seriously injure herself. Does anyone else have this anxiety? I just don’t want her hitting her head every night.
