To the OP (kcj748), if you are still around!- there are many, many good childcarers out there, whether nanny, childminder or nursery type setting. Its up to you to find the best option- not just financially, but the right fit for you and for your baby. Personality counts just as much as experience and qualifications, make sure the person or setting you choose has the same ideas about childcare and most importantly that the nanny, childminder or nursery staff seem to enjoy what they do and actually want to care for your precious child.
Exclusive attention isn't really nesesary. Many parents or carers of more than one child can still provide a loving a safe environment, and so can a childcare proffesional. Its actually rarer to find a nanny caring for a just one child, as its fiancially more of a strain (costs the same to the parent for however many children they have) and because many nannies prefer more children. I took my current job over another offered for a few reasons including that this job had two children and the other one child. More interesting, more of a challenge, more to do and learn! Plus children do need time to themselves, when they are not being stimulated and played with. They need to learn to play by themselves, to not have constant attention and interaction.
If you're worried about leaving your baby in another persons house, a nanny really is your only option. You have to weigh up the compromise- yes it costs more but the care is in your home, nanny (if live-out) arrives when you want them to so you don't have to get baby ready and out of the door. Nanny looks after ill childre when a childminder or nursery wouldn't, takes kids to doctors appointments or to get haircuts etc if you want them to. You can specify what the child does in the day, if you don't want nanny to take them to one particular park or if you prefer outdoors trips are only in the morning and craft in the afternoon you can do. You get a lot more say. And most nannies do nursery duties, so childrens laundry would be done, cooking and freezing food for weekends if you want. In past posts I've done drycleaning and taken parcels to postoffice, sorted childrens clothes and been in charge of replacing them as the child grows.
