Hello all - first time mum and first time posting! We've just moved house and i'm taking ds for his 8 week jabs back at our old GP this week (not poss to register more locally in time to get appoinment nearby). Stairs on tubes and trains on the journey are v steep so not keen to take him in the (harness-free) pram and taxi fare is on the huge side - so wondering if a sling would rub his thigh on the sore bit or if it might help soothe him and be better? We have an ergobaby, so supports from bum to knee. Any advice appreciated!
