Please help, freaking out a little

[Calluna]

I did something silly, I GOOGLED a symptom!!
Now I've gotten myself a bit worried I need someone to calm me down lol

For the last week or so my DS has not been sleeping much during the day. 30mins to an hour at most in a 12 hour period.

The last 3 days he has been refusing solids, I have only tried one food but he liked it before. BF have been much better the last few days and he'll have quite a few throughout the day so he's fine in that regard. (thanks to some good advice from some other BB members )

Just now after a feed he was lying on his tummy and he vomited a littl bit, maybe 3/4 of a tablespoon, and it had a slightly green color. Haven't seen that before, so I googled it, all the google results said stuff about an intestinal blockage and go to emergency

He did a poo just yesterday afternoon, which was runny, but I put it down to him not having had any solids in the last 3 days and it going back to breastmilk only consistancy, IYKWIM?

Should I be packing a bag and running to hospital or is there some other possible explaination?

ETA: He's been a bit grumpy too but I had just put that down to lack of sleep and me being stressed
