If you are working full time I would go with a nanny share without a doubt. They are likely around the same price, though nanny share may be slightly higher. From the adults side the plus points of a nanny share is that at least half the time you don't have to drop off and pick up. Every day, 5 days a week, for months on end, getting your little one to and from nursery can be tiring and stressful. Second you will almost never have to appoligise to your boss about taking time off work to care for your sick baby as a nanny is perfectly able to stay at home cuddling, administering calpol ect to a sickly child, where a nursery sends them straigh home. As your little one gets older they will make increasing messes with messy play, food etc. Your nanny will keep all the child related messes in order and do their laundry too! If you have to stay late from work for anything your nanny is often able to babysit. If you train breaks down etc you do not have to stress about being late to pick-up. Your nanny will be able to continue the weaning process, intrudicing your baby to great home cooked food and be able to discuss any feeding issues. Your nanny will also be able to help easily with potty training. From the baby's view point nanny's are also amazing. They have one relationship with one carer. They will both bond and your nanny will get to know your baby really well. She will be able to talk about how your baby was that day (feeling a bit off, hitting new milestones, hit a playmate over the head with a toy) and then discuss issues and how to tackle them. Your baby will also develop a bond with the other baby/toddler you share with as they will constantly see each other. Your nanny will be able to reinforce the rules you set and help your baby develop a routine, disciple and manners. Amazing how they teach them to share, tiddy up and not throw food! Your nanny should also talk to them constantly in effective ways and help with their speech, encouraging and correcting them. Finally you nanny will be able to take them out everyday to the park. museum etc. Make sure you have a nanny which drives and who likes to get out and about. It is wonderfully stimulating for the children to be in the different parks, groups and at the museums. There is so much for young children in the area and you nanny will be able to take advantege of it. Find the right family to share with before you find the nanny then pick the nanny together. There are a lot of wonderful nannys working in the Dulwich area. But the family can be more tricky in terms of how close they are, there budget, the hours they want, their views on doing paid activities and outings. Nursery's are also great environments, but I think they work best for part time working mum's. I work full time and my nanny (and the various shares I have had) have been crucial in allowing me to go back to work full time. Nursery is very tiring for a baby/toddler and they are shattered by the end of the week. But no matter what you do I agree with the advice above, do not mix! Your baby will be developping it's ability to attach in those months when you first start back at work. They will not understand the merry go round of mummy, nursery, nanny. It will be very stressful for them and you.
