feeds gone wonky, babyhas a cold and i don't want mastitis again!

[MerlinsBeard]

I had mastitis a short while ago and have been really worried about ds3s latch since then and him draining the breast properly. He now has a bug of some kind.
he is very sneezy, quite claggy (snotty in the back of his throat/high up his nose) and also has a bit of a cough. As a consequence, he can't feed properly and has been snacking. He usually feeds every 2 hours anyway which is exhausting enough but it got to a point last night where he was feeding every 30 mins-an hour for just a few sucks.

Now there is no knowing when he will next feed again-he is finally asleep and i really want to leave him until he wakes. My breasts don't feel full like i have missed any feeds (yet)

Am i worrying for no reason about him not being in his loose routine of every 2 hours ish feeding for about 10 mins from one side (his pattern)?

really want this to work this time and fit in a small amount of expressing without affecting my supply so that i can have a break every so often
