Cleaning the kitchen cupboards and organizing everything by size to the point that you make sure the silverware patterns match when it's stacked in the cutlery drawer. Sorting the baby's clothes over and over again is a favorite theme. Taking them out of the drawers and re-folding them, putting them away and doing it over and over again. Nesting will provide interesting stories for years to come. Perhaps you could do the planning and designing of the room and let someone else do the actual painting.
Paint is a substance to avoid for pregnant women.
Pregnant women should avoid exposure to oil based paints, old paint that may contain lead and some latex paints that contain mercury. Most water-based paints can be used but always check the label for contents that could be harmful. Painting should always be done in a large, well-ventilated area to minimize breathing fumes. Wear protective clothing and gloves and never eat or drink in the painting work area. There is no evidence to suggest that there is any link between the use of household cleaners and birth defects.
