The harder you find it to fast the more reward you will get. You have approximately 6 hours of rest and you should think of the most efficient way to use your time.
Most countries do not give holidays during Ramadan and you should continue your life with your normal daily activities.
Instead of thinking about how hard Ramadan is, you should think about the less fortunate who have to go through harder times than this all the time everyday. Ramadan is a time that we learn and appreciate what we have.
Think of it this way. On the day of judgement when Allah asks you why you didn't fast will you say because I had a job and my child woke up early?
There are countries which have less days than England but there are countries such as Sweden where they have to fast for nearly 22 hours and so they only get 2 hours break. They also have their jobs to attend and their families to look after.
The best thing to do is have a patience and do your best to fast as you are being tested by Allah to see how strong your Emaan is.
Remember: “Allāh does not burden a soul more than it can bear.” (Al-Baqarah: 286)
Have a blessed Ramadan and may Allah reward you for your fasts and struggles during this holy month.
Verse 2:187 of the Qur’ān explains this matter.
The Saudi Fatwa Committee stated on this issue:
“If the night and day are both distinct no matter where it may be, Muslims in Ramaḍān must fast from Fajr till Maghrib, whether the day is long or short.”
Shaykh Hasanain Makhlūf said:
As for those countries in which the sun rises and sets every day, with the day lasting for about twenty hours, Muslims living in those areas must fast from Fajr until Maghrib, except if doing so leads to some harm, severe sickness or death, due to its length.
The Qur'an:
"…and eat and drink until the white thread of dawn appears to you distinct from the black, then complete your fast till the nightfall. And do not have sexual relations with them while you are in devotional solitude in the mosques. These are the limits (set) by Allāh, so approach them not. Thus does Allāh make clear His Signs to humankind that they may become pious.” (Al-Baqarah: 187)
The people addressed in this verse are able to distinguish between night and day, the white thread of dawn being distinct from the blackness of night
