My third dc.. quite an age gap between first and last.
My first had severe reflux and wouldn't sleep unless rocked and I kept the house silent as he slept whether day or night ( easy as was the only child)
Second dc I refused to do the same and although occasionally had to be rocked or held to sleep, I vacuumed and got on with housework from when they were newborn so they would be used to noise. Tbh this dc had no reflux or issues so was easy and a good sleeper regardless but then they couldn't sleep in silence so would always need some kind of white noise.
Now onto the third dc..I thought I would have this down by now but this one also has reflux so at times would literally only sleep if I held and rocked and now seems to have got used to it and can't get themselves back to sleep
I do keep tv on while they sleep as I have 2 others so no chance of silence here but they only sleep 30 mins max and I find myself just sat still on the sofa next to the carry cot so they won't wake up.
I've started to leave them upstairs for the first nap of the morning with white noise on and the movement and video monitor but they are only 3 months, this is really bad isn't it?
