So many good suggestions and thoughts; it's really now you have to do something about that and tell all of us how you implemented it.
Apart from very good suggestions and ideas, I would like to mention that pregnant women are entitled to maternity leave as per the act. Also, under labor laws, there are provisions for a short recess for feeding. You can go through those rules, then chalk out your plan, discuss the plan with all the women, reach a consensus, and present it to the management.
I have witnessed many organizations relaxing norms of maternity leave and approving leave as per individual requirements (not 6 weeks pre & 6 weeks post), though the total number of days is kept the same. Organizations also go to the extent of offering leave without pay in addition to the above benefits.
I would further like to emphasize the following: All pregnant women should be shifted to one room or any corner of the room. Some good photographs of children, animals, good thoughts can be pasted on their dashboard and also on the notice boards. Good books on pregnancy are available in the market and can be kept on a central table. One flower pot with flowers should be changed every day. Pain relief, anti-vomiting, fever, common cold tablets can be provided, apart from pain relief balms. Importantly, office chairs should be replaced with easy chairs. The pantry may be advised to keep chocolates, health drinks, milk, and juices with a delivery option on the central table. Rules for uniforms and shoes should be relaxed for all the 4-5 females.
There could be numerous things that can be done. Please go ahead and do it. Don't forget to put up a poster indicating "WE CARE THOSE WHO CARE FOR OUR ORGANIZATION, AND WE CARE FROM THE HEART" or something personal and emotional in nature.
Do convey your successful implementation... all the best...
