Can your baby nap through noise?

[WillSingForCake]

We tiptoed round PfB when she had her naps as a baby, and as a consequence she now wakes easily if anyone so much as sneezes near her.

DC2 is 6 weeks old, so thought I'd do things differently and let him take his daytime naps downstairs. But the poor child keeps waking and crying at noises, particularly as PFB is now a noisy toddler. He gets overtired as a result. So what shall I do? Persist, or let him nap upstairs in the peace?

I'm with the nature theory. I think some babies sleep through noise and that's nice for their parents but they sleep despite the noise rather than because of it.
