Firstly I wouldn't be happy for her to have them on her own, but that's more an issue with D than her. It's not just the emotional side of being left with someone they don't really know. Its the safety aspect, any parent would understandably worry about whether they would be safe with someone who doesn't have children.
However as far as holding them, kissing them, hugging them, I'm ok with it!
I think if I put them in nursery, they had a childminder or nanny I'd want their carers to treat the boys how I would. I'd want them to make the boys feel safe and secure when they arn't with me.
I'd be lying if I didn't admit that at first there was a pull in my heart, a sickness in my throat when I saw A kiss Moo for the first time. There was no jealousy though. I know that to the boys I will always be there Mama. You can see it in there eyes, the way they light up when they see me. When they are sad, I'm the one they run to. When they need reassurance, they come to me to encourage them to go that bit further. As long as I carry on being the best Mama I can, I hope they with always feel the way I do about them. That this bond will only strengthen as the years go on.
