As above, I have a 6wk old who struggles to stay asleep during the day when my toddler is awake. I don't want to have to keep my toddler quiet and I want my baby to get used to the noise so I usually put him down to sleep in his swing in the loungeroom. His best and longest sleep during the day is at midday when my toddler is also asleep (I keep the radio on so there is still noise).
He's quite unsettled during the day as it is so it may not totally be the toddler waking him, but I'm sure it is alot of the time.
Do they get used to the noise, sudden shrieks and thumping footsteps? And if so, how long does it take? Do you just keep them constantly exposed to the noise?
Today I had to resort to putting him in his bed with the door closed though just to give him a good sleep.
