Hello, I'm new to this. My baby is 2 weeks old today. I bought a second hand next to me crib and a brand new matress. I have found that there is gap between the matress and the side of the crib (on the longer sides) which I can easily push my hand into. This doesn't seem safe to me. I therefore ordered another brand new matress this week directly from chicco but exactly the same thing is true. Is this the case with all of them? Is this safe? Thank you for any feedback, from an anxious new mum
