Baby number one is due in August and will be a first grandchild for my MIL. She lives overseas and wants to come and visit for a week soon after the birth (staying in a hotel). The date she suggested arriving today is 3 weeks after the due date, which panicked me. It feels far too soon - what if baby is late? She'd be here just a week later! So. It's going to upset her but we need to put her off. When would you suggest...?
