The weather at this time of year can be extremely unpredictable so be style savvy and wear lots of layers. Cardigans, sweatshirts, denim jackets and even leggings under dresses are great pieces that can be removed or put on as the temperature changes.
Comfortable shoes are a must. A family day out can involve a lot of walking so it is perhaps not the best place to try out a new pair of shoes or heels for the first time.
Invest in a good sunhat and sunglasses for both you and your children. After a lovely day out you wouldn't want to end it with a horrid case of sunstroke.
Pre-apply suncream before you leave for the day as this not only saves you the sticky hands and the unenviable job of chasing a giddy child around, it also gives the cream a chance to sink in and do it's job.
Take a scooter or buggy for little feet. Whipsnade is huge and Daisy would never have got around it without the aid of her buggy. Some of the animals enclosures are quite far apart so a scooter or bike will be a huge advantage for you and them.
There is also a bus that goes around the venue or you can also take your car in for an extra fee.
Have a plan of who wants to see what before you go. We knew Daisy wouldn't make it around the entire zoo so we asked her beforehand which animals she really wanted to see. It's also advantageous to get there early to avoid the rush and queues.
Picnics are always a good idea. Eating at some of these venues can be pricey and when everyone all wants to eat at the same time the queues can be big! Save yourself the wails of a hungry child (and some money) by packing a picnic.
A mini first aid kit is a must. With all the running and scooting, an accident is sadly inevitable. Plasters, antiseptic wipes and hand sanitiser should cover most injuries.
And most importantly, have fun!
