ok to install window grill when pregnant?

If you are worried about the dust, don't stay in the same room or stay out while they install the grilles. Don't need to believe in superstitions. Anyway as a new mum you will be too busy with the baby to install it after birth. Imagine having to bring the baby out during grille installation, do thorough cleaning ensuring he/she don't accidentally touch & ingest the dust, and then also having to care for him/her.. don't forget you also have to BF/pump on a schedule.. It's just easier to settle before the baby is here
