FTM- 3 month sleep/eating change

So

My daughter is 14 weeks today and has been sleeping more the last 2 days and eating less. Also, she’s been spitting up a lot more when she eats as well but mainly in the mornings. She has been a little fussy but not too bad!

She starts eating, 10 mins later she stops, spits up and then goes to sleep. She hasn’t been up longer than an hour stretch and then sleeps for about an hour +...

Growth spurt, sick or just a normal baby ?
