Hi, im planning on travelling to France with my almost 3 year old to see family in France. Im not confident driving abroad so hoping to use public transport. Flying there to Charles de Gaulle and then either train or bus then train. How on earth do I cart luggage, pushchair and possibly a car seat by public transport? Is it best to buy a car seat there and leave it? Even without the car seat how do I grapple with grumpy toddler and bags? Advice please!
