When Maddie was just a few mths of age she stayed at my MIL's for 2 nights every 3 weekend. It killed me so I changed my work schedule. Since that, she stayed overnight with her childminder when Shannon and I had horrible food poisoning and we couldn't look after her because we were so sick.
Other than that, she stays with her childminder for 12 hours up to 3 days a week when I work or occasionally with our neighbor friends. Maddie has no stranger anxiety and is so independent away from us so it makes it easier. Everyone loves looking after her because she is so easy and loves to be with people
