How could you be doing any better for your dd? Spending time with her and helping her learn about the world. Why is it that nursery is thought to be so much better for the child? Nurseries were set up for the convenience of the parent. The child's needs are secondary. By that I mean the system was not set up to satisfy the needs of the child, it was set up so that parents would have somewhere to leave their children so that they could work. Creating them to serve children's needs came after that. I'm not saying that nurseries are bad, but I think they are a compromise. They cannot provide anything for your child that you cannot povide yourself given the time and inclination.
I think some working mothers choose tp have the view that if you stay at home you spend your days toing housework and watching daytime tv. I know I certainly don't. We go out to parent and toddler groups, activities, for walks,to visit people, we play games, colour,paint, make tents in the garden, cook, sing songs, read, build things, make things, play with playdoh, play with cars, dolls...you name it, we do it How can nursery compete? We do what we want whenever the mood takes us so the children dictate the pattern to the day - rather than having it dictated to them (this is part of the reason we are planning to home-educate - so this can continue - but that is another matter).
There can be nothing more wonderful than spending time with your children, watching them learn, grow and develop. Something you undoubtably miss out on if someone else is caring for your child. I know I wouldn't change it for the world. I also think we have a very strong, close relationship because I know my kids better than anyone - I am with them 24/7. Kids grow up so fast. I'd hate to look back when they're all grown up and wish I'd spent more time with them when I had the chance.
Don't listen to what anyone else says. Do what's in your heart. I believe you're doing the best for your child, and if you do then nothing else matters.
I know I'm going to get into trouble for what I've said, but this is a forum for free speech and I have only said what I believe. I don't want to offend anyone, it's just the way I feel.
