Hi Sharon,
NJ hey, I'll actually be in East Hanover for a few days the week after next! I'm going to guess your partner works for Novartis, or failing that Roche, as it seems quite a lot of the people who move here work for one them. Or maybe that's just the view from inside the Pharma industry bubble
One piece of advice I'll offer for when land here, specially with little kid, is food - the supermarkets all close by 2000 on weekdays, 1800 on Saturdays and don't open at all on Sundays. This caught me out when I first got here (was used to hour 24 hour shopping in the UK

) and my first meal was some horrible dehydrated microwave thingy from a petrol station!
If you land late, there's a small Co-Op in Badischer Bahnhof that's open 0500-2300 every day.
Hope this helps, but if you need any other pointers as to where find things when you get here feel free to ask and I'll do my best to help!
