"just to point out my dd was excl bf and I left her for 4hrs a day for three days when she was just 2months she did not perish and she wld not take my expressed milk. she was well nourished and had actualy jumped 2 centiles before she was 3months"
Some mothers and babies can go long periods in between feeds and still sustain exclusive breastfeeding. Many others can't.
And the op was about a 3 week old baby.
"When he is at nursery he is with other children he likes and plays with"
That's very forward for a 6 month old. Most children don't play together until they're toddlers.
"If you are going to be a good, attached, interested parent then you are going to be that kind of parent in the time you have with your child, no matter how short that time is. If you are going to be a detached, emotionally absent parent, you are going to be that kind of parent even if you spend all your time with your child."
Nobody here is going to deny that the relationship between the parent and child is the most influential factor, and can make up for a lot of things. This has always been the case - even in situations where children are getting VERY suboptimal care in poorly run institutions (and there's no doubt that there are some stinkingly poor nurseries, childminders and nannies out there).
But again - want to come back to the point that the OP is talking about a newborn baby, not a toddler or an older baby who has already built a relationship of trust with a parent.
"I was hoping that you would tell me that you appreciate that not everyone feels that way. But that it doesn't make you any less of a mother".
I do appreciate it. And I'm in awe of mothers who care beautifully for their babies when there is a dearth of passion there to carry them through the early difficult days. That's true dedication.
"So say you felt this way about one of your children. But it was harder to bond with middle dc.
So how do you expalin this."
Don't know that I can explain it. I had a difficult birth with dc2 (shoulder dystocia at a homebirth) and he was very different to dc1. Maybe this made a difference. I was hugely attached to him and couldn't be away from him, but there wasn't that same sensation of passion - my heart beating faster when I thought of him. Very strange really. I'm madly in love with him now.
