Hard work will pay off

It seems like the only time I get a chance to write is in the early am (like it's still dark outside am). With Kinley growing a little bigger each day, she's awake for longer periods of time trying to absorb all her new surroundings. I especially love how she tries to follow me with her eyes when she hears my voice in the room. She sleeps fairly well but the only sleeping issue we have is that she loves to lay on her belly. I could definitely use some advice on this matter. We don't have any soft bedding in her crib,she literally lays on her mattress and a tight fitted sheet. It freaks me out and I can't sleep more than a few minutes at a time because I'm constantly getting up to look at her. I've never had this issue with Presley (probably because she never slept) but I could use some advice.
Other than the belly issue, all is good here at the Jones residence. I'm trying to keep Presley on her regular nap schedule and sometimes it works out to my advantage because they will BOTH be taking naps at the same time. It can get a little crazy around here trying to get both girls on a schedule/routine and being sleep deprived makes it a little more challenging, but I always tell myself that this phase and it's temporary and all this hard work will pay off once they get a little older. Until then I'll enjoy these nice quite moments (when they rarely happen haha)....
