Terrified

So for the past 12 weeks I’ve spent every second with my baby girl, we co-sleep, when out and about I mostly wear her in a sling, I exclusively breast feed too. And tomorrow I’ll have to leave the house for about 3-4h, leaving baby with my mum ( and partner when he gets back from work like 2h before me ) I am terrified of leaving her behind to the point where I feel sick thinking about it. When I think of the sound of her intense cry I feel terrible. Only me can calm her down... Will she be able to settle in somebody’s else’s arms? Will she cry too much and pass out?

Any good experiences appreciated, if anyone can relate...
