My daughter turned 10 weeks old today and since yesterday has been really grumpy and not herself. She sleeps well and goes from 7/8 till around 6/7 in the morning, this hasn't changed but she normally sleeps well in the day, she would have 5/6oz bottle every 3-4 hours now suddenly she's screaming like a mad woman and wanting fed every 2 hours. Is this a growth spurt? I've never noticed her have them before. She goes bright red just screaming like she's in pain but is calm after the bottle for a bit. She screamed so much earlier she started to like choke or gag on all her saliva. Then I'm blubbering like an idiot cause it terrified me. Has anyone else's baby done that? We have a doctors app tomorrow for her vaccines so I'll explain all them but looking to see if anyone has experienced it.
