Nannies really make your life easier - no need to get child up in the morning, push a pushchair in the rain or the cold before or after a day at work. And, as others have mentioned, they'll provide your child with lots of one to one attention. I couldn't afford it unfortunately. We went for a nursery instead and it's been great and made her very sociable. I was lucky my daughter was hardly ever ill but this could have been a problem as nurseries (like schools) don't take kids for two days after a vomiting episode for example. Something to bear in mind. On the negative side, I noticed her speech would develop very quickly when she spent a week with us when we were on holiday so I do think nursery wasn't a great place for her to learn to speak (too much going on, too much noise). Fast forward to year 3 and she's a very articulate little girl. My advice when it comes to childcare is always not to set your heart on a specific solution. Go with the best person(s) you meet at the time -- whether they work in a nursery, or as a nanny or childminder. When I walked into her rather shabby nursery and saw the smiles on the ladies'faces, I knew this was the place.
