clingy sleeper

So I know that around 7 months babies get clingy with mommy, and I'm seeing a bit of that during the day, but my baby won't seem to stay asleep unless she's next to me, and even then, she wakes up every hour or two to nurse. She's EBF and we are slowly starting solids. I'm exhausted and feel like she'll never get back into her crib and sleep for more than two hours at a time
