Hello, congratulations on your progress so far
Sorry that your poor lo has reflux, but well done you for spotting it.
I think that you could make as much noise as you liked when she was in the swing b/c it keeps them asleep 'artificially' (for want of a better word). It's like when they fall asleep in the car, as soon as the car stops, they wake up, it's the same with the swing - it's the motion that keeps them asleep, but it's not as deep or restful a sleep as it is in the cot. In the cot, it's her body that's regulating the sleep cycles, so the sleep is much better for her, much more refreshing.
Anyway, I know I always used to sneak around the house when lo was in bed, but I came to realise that I could be much noisier than I thought, it just depends on his sleep cycles. I discovered this by accident when I didn't intercept the window cleaners in time, and they slammed a ladder up against his window, and proceeded to clean it noisily - he didn't stir
. What I do now is always be aware of the time - I'm very careful about noise when he's transitioning between sleep cycles - so, 45 minutes after he fell asleep (and about 5 minutes either way of that time). That's when it seems to be easy to disturb him, any other time it doesn't seem to matter. I think you just have to experiment - you just have to be brave
.
One thing I did find to be helpful is if I know there will be some noise is to have some continuous background noise - like the radio or TV on in the lounge. It seems to help, softening the impact of any sudden noises (like doors slamming, etc).
With the reflux, I understand that she may be more comfortable if you elevate her matress at one end (like you do when they have a cold) - have you done this? Also, have you checked out the reflux board on this site? It's a mine of useful information about it, and could really help you.
