9 week old suddenly fussy won’t attach?

I have been exclusively breastfeeding my 9 week old and he has been an awesome baby!

He has had a bit of a cold the last couple of days and now for some feeds he suddenly just screams and won’t attach. He will settle if sitting upright, but has no wind or reflux etc. more like he just wants to see what’s going on!

Thought it might be because my letdown was too strong so have tried pumping a bit beforehand and hasn’t helped. He will be happy but showing signs that he’s hungry (sucking hands, and searching)

Unsure what to do! He is still sleeping fine and wetting nappies. I thought maybe he needed to do a poop, but he did one this morning and it was normal 🤷🏼‍♀️

Any suggestions on what this could be?? And how to help him the feed again. I’m a bit stressed about it all after my first being a prem baby and having low supply issues and latching problems. 😓
