Moving to Bahrain from Canada- Expat feedback

Hi! My husband is originally from Bahrain but has been living abroad for many many years. I've visited a couple times and now, due to personal reasons, we're planning on relocating to Bahrain with our 2 year old son. I wanted to ask for honest feedback on what is worth shipping and what not., etc. The feedback I get from his family is from people who have lived there all their lives, but I'm more interested in knowing an expats point of view on different topics:

1. Shipping personal items- Is it worth shipping our cars, household items, small appliances or even my Le Creuset pots?
2. Jobs- How is the job market there for Expats? I plan on enrolling in an Arabic course when I arrive by my knowledge of Arabic is cero.
3. Daycare/Nursey- My son is currently attending daycare. I've started researching but it seems in Bahrain most facilities are more of a school than daycare. Here he attends 5 days a week, 8am to 4pm and they provide food for them. How do working parents manage over there?
4. Allergies- My son has peanut and tree nut allergy, which makes me nervous. In Canada they're pretty good with labeling peanut free foods and at restaurants the same. Also, daycares have a Peanut Free policy which gives me peace of mind. Is there any awareness of Peanut allergy in Bahrain? Use of Epipen, etc?

Thanks in advance for any input...I want to be as informed as I can be before I arrive.
