We have a 6mnth old baby. Wife's sister buys baby a lot of clothes as gifts. Maybe 80% of his clothes. Whenever she comes over she assumes she will be the one who puts the baby to sleep and calls herself the baby whisperer. When the baby wakes up before we can get up, she will say that she will handle it and runs to placate or feed baby. Today she bought him a 5ft tall giraffe. It looks very expensive but neither wife nor I like it. My wife has moved the toy out of the nursery as she thinks it is creepy.
My wife told me her sister would love a baby but has a medical condition which means conceiving will be difficult. AIBU in thinking SIL is almost trying to mother our baby?
