When packing for a holiday with small children, you often find yourself taking far too much. You may have created a list of clothes but then you also need to consider any games, books, swimming outfits, coats and shoes you want to take with you.
If holidaying in the UK, you will need to pack clothes for every eventuality as you never know what the weather is going to be like. I found myself having to take a few changes of outfits for my children which needed to be suitable for warm and cooler, dry and wet conditions. This very quickly filled up my suitcase but as we were not flying anywhere, luckily, I did not have to worry about luggage restrictions.
If you can, try and find a few outfits that can be worn in all-weather such as a pair of shorts, but that can be teamed with a cardi and tights should it get cooler.
