we are going to bil's wedding next month with ds(10 months)because we live 1hr away from mil their friends (they've got loads, 12 came to our daytime wedding doo)except 1 haven't met our ds. we may not be there that long, it starts at 4pm ds usually goes to bed about 6ish but i'm a bit concerned i'll feel a bit overwhelmed by it all. any tips?
