Advice please... newborn non stop crying

Sarah

Hey ladies, today my little girl is 3 Weeks old and she has been fussing all night and day. Feeding almost every hour and crying her lungs out in between. Nappies are good so I don’t think the milk is a problem (im breastfeeding). Could this be a growth spurt?

She has been spitting up quite a bit as well.

Any advice or anyone else experiencing this?
