DS is 14 months old. Since we stopped breastfeeding cold turkey about 2-3 weeks ago (may or may not be related to abrupt weaning) he seems to have lost a lot of his attachment to me

Sometimes he cries if SIL or DH pass him to me. This never ever happened before as I was always his *favourite*.

Has anyone else experienced this? Is it a phase?Or a developmental milestone of sorts? I feel hurt about it but should I?
