I know this has been done time and time again, and I guess I'm just after more reassurance!
DD is five months old, just. She can roll both ways, from front to back and back to front. We co-sleep. Until now, she has slept on her back until her first feed, then on her side (I fall asleep as she feeds, and she stays like that on her side).
Now she can roll she always rolls onto her stomach to sleep. I put her back on her back, but by the time I wake up again, she is back on her stomach.
I have been worried because our mattress is quite old (possible over-worrying here), so I have put her brand new, firm cot mattress on our bed, and she is asleep on that. She will spend most of the night on her stomach.
When it gets to about 4am, I relax a bit and let her stay on her belly, so I get 90 minutes of good sleep. My totally illogical reasoning being that at 4am it's almost morning so she'll be OK.
But for the rest of the night before, I barely sleep at all as I'm so worried about her on her belly, and I keep turning her back.
I know it should be OK to leave her on her belly if she can roll, but she is only five months (and also, she is a very small 5 months - she is still wearing 0-3 months clothes, and is only on the 15 centile).
Someone give me a grip?
