We definitely worried about whether Inara was suffocating in the ergo in the early days. The first time we took her out orienteering, we stopped at least a half dozen times to check that she was still breathing.
Pretty sure checking if your kid is still breathing occupies 110% of a new parent's brain capacity.
At least when the cry, you know they are breathing?
That is totally normal and I think it's ok to check as much as you need to. In only a few weeks her head will be higher up and you'll see her face, so much less worrying needed.
Good to know that others worry too :) Today she was sitting off to the side a bit, so her head was turned and there was space for her to breathe. That made me feel a lot better!
I used to worry about that too. Both my boys got used to turning their head sideways which made the worrying less. I was told as a rule of thumb you should be able to kiss the top of their head and that means they're high enough up that it shouldn't be a problem :-)
