It's only for a few seconds - probably 5 seconds-ish, and it tends to happen in the night, in the bed next to me. I have a feeling my others did it too.
It's like he'll be breathing away, calmly asleep and then it will stop - ie he'll breathe out, and not breathe in for a few seconds. Like he's just forgotten to.
And then after a few seconds, say 5 or 10 (hard to quantify as I'm usually so sleepy) and maybe a small nudge from me, he will do a huge inhale of breath and everything is back to normal.
He is 6 and a half weeks old.
Should I be freaking out? It doesn't happen frequently - just now and again. I only remembered it during daylight hours yesterday, as he isn't a great sleeper so anything after dark kind of blurs into a long 'dream' iykwim.
He is healthy otherwise - normal weight, born at term etc etc.
