'why are new mom's soooooooo insecure?
honestly let her take the little one around the block in the pram! if your unable to have the little one away from you at all then seek counselling because you need help.'
This is ill-informed, patronising bullshit, frankly.
Bonding is an actual thing. Driven by hormones. Biological design to keep your baby safe by giving the new mother a very strong instinct to keep them close.
Seems some mothers feel it more strongly than others.
And yes you can override it if needs be (I've posted on another thread recently about spending 4 nights away from my ebf first born when they were four months because I had a sudden and acute illness that had to be treated).
But in general I didn't want to be away from my babies when they were little. It triggered my hormones to be away from them. I couldn't sleep.
It's not a rational 'I don't want this person to care for them' thing. It's primal.
DH found it hard to understand how difficult I found the hospital separation until I described it to him like this:
Imagine your hand needs treatment. And you have the best surgeon in the world caring for you. Who says ' we just need to cut it off and treat it in another room for a while'. You trust this dr. You agree with the treatment plan. But you'd still spend the whole time without your hand with your subconscious screaming 'where's my hand, where's my hand' until it came back.
THAT is what is being separated from my young babies felt like to me. So I didn't do it unless necessary.
I was, though, distrustful of people who didn't understand or respect that as I questioned their motives.
You do need to let them explore without you at some point. And that primal feeling gradually faded, or rather my happiness at being apart from them gradually extended from nine to an hour to a few hours to a whole day (went back to work at 7 months was fine) to overnights and a few days apart occasionally by the time they were 3-4 years old.
But the only reason to leave your baby at three months is if the mother wants to. And this one doesn't. So discussion over.
A guiding rule for me, still, when were pushed for stuff is 'in whose interests is this?'
DCs interests are paramount. We're not doing anything they are not ready for. PIL push for the DC to go there without us. But they are too young for the longish stay required (they live a long way away). So it's a no. But we might, now, leave them overnight as part of a visit when we are all there, now they are a bit older.
As the OP said, they are not toys. And some relatives have a hard time distinguishing between what they want and what is in the child's best interests.
