My baby girl has refused her bed time bottle for the last couple of nights. Even though it's been a few hours since her last bottle, she doesn't want anything to do with it. She just wants to go to sleep!

So far it's been fine. I put her in her crib, she sucks her thumb, and she's out. She sleeps through the night still no problem.

But she's only 4 months old, and from everything I read online she should still be eating that bed time bottle until 6 months. I'm assuming it's because that's when they start solids. My LO is bigger than most (17 lbs 5 oz at her 4 month apt, 95 percentile), so maybe that's why she's ok not eating the bed time bottle?

Does anybody have experience with this? Should I be worried?
