Bonbon8888 - It's natural for you as gp to want to hold, cuddle, nurse your new grandchild. It's also natural for a new mum to want to set boundaries and protect her baby even if her thinking is not rational. However, if her thinking is completely irrational then some intervention at some point will be needed. If she is so afraid of baby getting germs that her insistence on not allowing anyone to hold him/her continues for many months, and if she persists with the darkened noiseless room then alarm bells will be ringing. Sure the bond between baby and primary care-giver has to be developed, but research disputes the idea that a baby who is held by different people will become ill and the truth is that babies even at 8 weeks old need exposure on a gradual level to various bacteria in order to build their immunity. We know for example, that children who are exposed to cat/dog dander and who share beds with siblings/parents do not get asthma as much as those who are brought up in pristine environments, and that if babies have nut butters in their diets when being weaned, they don't develop crippling nut allergies later on. My advice Bonbon is to hang in there, ask your mil if there's anything else you can do to help her and as the months wear on, help her prepare for her return to work and the introduction of a child minder to whom she will relinquish all control, by reminding her that it would be a good idea for her to leave baby with a grandparent for an hour to gradually build up her own ability to hand over to a stranger.
