But I am pregnant, I would need to have him on the flight as I will have a toddler and will be about 30 weeks. He will have to accompany me. Will it be a big problem? He would stay till delivery. We would process the newborn's passport and then get back on the next plane to NBO. I'd then go back after the one year. Will that affect our petition, because I was planning on applying as soon as we arrive.
Travelling with a toddler isn't as bad as you seem to think - even whilst pregnant. You can book assistance and make sure you have smooth arrangements to be met upon arrival.
Now, you might also want to consider delaying the activation until after the birth. If you have to go down the F2A route, the current priority date is Dec 2013 - so you will have to figure out how to establish a home in the USA (without your husband being able to work), or perhaps activate and apply for a re-entry permit. However, you must remember that you will need to file an I-864 to sponsor your husband, so it would be good if you have settled and developed an income, otherwise you will need someone else to co-sponsor with you.
