When it gets really hot we have to consider how it may affect our babies.
The first thing is to shed the warmer garments and look for a selection of cool summer clothes.
If you are certain that the night time temperature is not going to change and cool down, you may even let baby sleep in a nappy and cotton vest.
You will find that the natural fibres, cotton, or a light open weave muslin will allow your baby's body to regulate its own heat.
If you feel the little one may feel chilly in the early hours of the morning you may prefer to dress him or her in a light weight sleeveless sleeping bag.
These keep the legs lightly covered but not overheated.
If your baby is very young - under six months, you may be wondering if it is safe to give him or her water to prevent dehydration.
This is rather controversial.
Many moms and paediatricians believe introducing water at an early age could upset their electrolyte levels with dangerous consequences.
Others say that is nonsense, but few advocate more than a few sips of water at a time.
Probably the most sensible way to handle is to allow the baby to drink milk formula, or suckle ad lib.
They tend to know when they need more to drink.
The other thing is to keep a close watch on whether they are still wetting their nappies the same amount as usual.
If they are staying dry longer, perhaps you should consider giving a little extra water.
What is most important, if you are feeding baby yourself, is to make sure you are hydrated.
Drink plenty of water.
Don't count the tea and coffee because they tend to have a diuretic effect on you, and will actually dehydrate you more in the long run.
For during the day you will find huge selections of the most gorgeous summer clothing for baby boys and girls.
Many of them are certified organic, which means that the fibres used for the materials will not have pollutants such as insecticides on them.
The natural fibres will be cool and comfortable for these tiny people and will absorb any perspiration easily.
You will need to take care on these really hot summer days that baby's delicate skin does not get burned.
Remember, in shade and even reflected sunlight from shiny surfaces can give them sunburn.
If there is glass between them and the sunshine, they will not get sunburned, as the ultra violet rays cannot penetrate glass.
However they can get really hot, even to the point of heatstroke.
When it is cool, in the mornings and late afternoons, do let your little one expose his or her skin to the ultra violet rays of the sun just a few minutes, if possible every day, but at least three times a week.
This is really important, as Vitamin D is produced by sunlight on the skin and this helps bones and teeth to develop normally.
