my dds slept right on my chest for the first 2-3 months. they were facing me (so technically on their stomachs, but this is not the dangerous thing you have heard about IMO, the danger of stomach sleeping has a lot to do with the flame retardant in the mattresses offgassing (IMO) and a baby not being able to turn his head if his mouth and nose are against mattress. If on your chest, this is not the case (IMO) . I did not wear any top in those early days, no pillow and thin blanket only to my waist when they were infants. when we would wake to nurse every 2-3 hours, I would feed them for a bit doing side lying nursing, then back up on my chest so I could go back to sleep safely. I have a bed to myself btw (well except me and the baby, I mean, no man). I wouldn't want an animal in my cosleeping bed either, but a dog that stays at the foot of the bed shouldn't be a problem. I understand your hesitancy about the mattress. If the baby was to lie face down on it, that could be dangerous because it is so soft. Is there a firmer mattress in your home? Once the baby can turn his head, it will be different. I agree with pp though, as long as baby is on your chest, it shouldn't be a problem. Just make sure you are awake during nursing until the baby and bed are safe for one another I would say, unless you have boobs that baby can eat from while staying on your chest... then you got it made. change the temperature of the room? I have a room heater that works without fire danger, and eden pure for my room only, very efficient. I used a vaporizer that put off heat before I had this. cost $12. It kept room at a balmy 72. I do not think having the baby on a pillow is the same as on you, there is a connection that exists in sleep when the infant is on you IMO. Having a baby on a pillow does not sound as safe to me and I would recommend no pillows or heavy blanket. If others are in your bed, they should have their own blanket of any type and be way over on their side of bed with their pillow. It sounds like your baby knows what is best, to be with momma, now making the bed safe is the next step. Perhaps a mattress cover would make it less 'giving'? If you would feel safer, you could make a pallet on the floor for now.
