DD is currently 4 months old, around August/September time we’re hoping to visit in laws. We will be going via train so can’t take too much really, just wondering for some advice on the best way to go about this e.g. sleeping when there as they don’t have a spare room so would be in the living room, what to take and any more helpful advice. I should also add it will be in the city so quite a busy place. Thanks in advance!
