Because this happened today:

We only put him there for naps, and we ALWAYS strap him in. I was just testing what he would do without the straps while spotting him. He was laughing as he tried to climb out.
I feel the pictures are good evidence to make sure the grandmas use the straps!
DS1 happily lounged quietly in the RNP until he reached the weight limit.
Re: Anyone still in the RNP?
I caught her pulling herself up by the dangling mobile thing last week! This girl has amazing core strength and can sit up without grabbing anything. We are still using mamaroo, swing, and RNP but never unattended anymore. I love watching them grow up but seriously... My life gets so much more difficult when they become mobile!
