Everyone has to decide what's right for them at the time.
I personally don't believe in having children and passing them onto childminders or relatives. BUT, before you all jump down my throat, I also can see and believe that some people really don't have any other choices, and respect them for seeking the best for their child.
I decided to be a stay at home mum, when I was pregnant with our 1st. Even when my hubby was made redundant, we both still decided that I should be there full time. Our son didn't start nursery until 4, so he was with me day and night. I'll admit it was very hard sometimes, but I didn't care as long as he was with me. I used to take him out, go to play groups and do everything together. It was harder for ME, when he started nursery, as I found myself alone, until hubby got home. With all it's ups and downs, I am glad I did it that way, so I didn't miss a minute of his younger life.
With our daughter, I was still home, the same way, except we put her in a private nursery before she was 3. The reason for this was that, she was very inquisitive (sp?) and liked to mix with people, even at such a young age. That was the best thing we did for her. She could read and write by the time she was 3 1/2. Now in year 1, she reads year 3 material, given by her teacher. She is really confident, and makes friends really easily.
I guess things could have gone the opposite way, and we could have regretted our decisions.
I suppose what I am trying to say is, that at the time, we don't really know which is the right or wrong way. We make decisions based on financial matters or any other situation, and hope that it's the right one.
I am sure you made the best choice for your daughter, so don't let anyone make you doubt yourself. Your daughter most definitely has a much better quality time with you, than your neighbour's daughter does with her. I can't see how anyone with a character like that, can give her daughter the good upbringing she should.
After all, they do say "It's quality not quantity that counts".
Just ignore her, and enjoy your daughter and pregnancy. Once these days are gone, they'll never come back.
