My twin girls have just had their 4th birthday - we had a party and invited their friends from kindergarten. I've since found out that around here people dont really start with birthday parties till the kids turn 5 or 6. Anyway, one of the little girls who came (and brought lovely presents) has her birthday this week. Should we get her a present, or will it come across like I'm trying too hard? I am a bit anxious about my girls fitting in as we're foreigners.
