In this country it's never really a certain of how the weather will pan out, therefore prepare for the unexpected - pack a light rain jacket and an umbrella just in case. It doesn't take up much space.

Choose any outfits the night before and lay them out for the whole family, easily accessible for the next morning. It's also a good idea to get the kids involved so they get excited for the day. 

A pocket mirror, lipstick/lip balm, hairbrush, hair ties and clips will prove very handy for windier days. As will tissues and wipes for mucky hands or runny noses. SPF and insect repellent for hotter days.

For younger kids, bring along a spare set of clothes in case of accidents and also an extra layer or two for unexpected weather changes. Avoid busy patterns, logos, or very bright colours as they can prove distracting. More in depth outfit advice here.

For younger kids bring along their 'can't do without' items (that you perhaps have 2 of) whether that's a comfort blanket or favourite toy just for reassurance on the day. I would avoid screens as they will be more hindrance than help.

Without a doubt, bring quick, mess-free snacks (think little biscuits or fruit snacks) and water bottles to keep everyone happy, primarily toddlers and younger children. 

I always ask clients to bring along a blanket for sitting/lying down shots if the ground is a little damp. It's also good for younger children who are for eg learning to walk or crawling plus, adds some variety to your images

It's slightly trickier to opt for a completely different outfit outdoors so instead, choose 2 or 3 different items to accessorize such as a hat, scarf or item of jewellery to vary your pictures and outfit.
