Autumn does. It's one of the first noises she makes in the morning and she's quite good at it. She doesn't say "quack" but makes a throaty noise that sounds just like a duck. She also knows where airplanes are and points to them anytime we go outside.
The big news of the week is that she's been sleeping in her own bed for five nights now. I didn't openly share that we were bed-sharing because I know a lot of people frown on it but she's been sleeping with us since she was born with some nights in her co-sleeper. She's definitely outgrown that and I'd had enough hair-pulling and groin kicking so I reluctantly put her in her crib. She did wonderfully, she puts herself to sleep and sleeps for almost 12 hours! She's such a big girl now.
