The attachment relationship cam be affected by daycare if the promary caregiver becomes the people in daycare.

A childs temperament settles after 3 and imo 0-3 is a critical period for bonding with the parent.

I would suggest a healthy mix of some daycare and some stay at home parenting, so the child can better socialize with other children and learn from them, but also grow a secure attachment to their parent and observe the adult world, not just what other children do.
