Name changed as outing.
This was yesterday. In supermarket with DD 3 year old DS and 14 week DD. DH had the pushchair & I had the trolley. We were in a bit of a rush so DH said he'd go get a few bits and we'd meet in the middle. Off he goes and takes the pushchair with him. DS stayed with me. Had a quick look at the baby clothes for DD. Left trolley at end of aisle. Wandered up another couple of aisles then turned round and automatically put my hands on the pushchair that was there. Started walking off and DS pipes up "that's not my sister" I looked down and realised DD was now wearing boys clothes and had aged by about 6 months. I panicked and returned baby to the aisle I stole him from. Thankfully I'd only got to the end of the aisle and turned to go into the next aisle before DS said something. The other mum never even noticed!
