There's some nonsense on this thread.
When ours were tinies, I thank my lucky stars that DH used to bring me a cup of tea in bed and the baby at 6am; later the baby and toddler. Then, at about 6.45 he used to go to work, on the tube, and stay there until he came home at 9pm. He missed so much, he really did: he missed the tantrums, sometimes mine, the occasional pig lazy day, the cake on the carpet, etc.
To be fair once dd came along, it was out of the house by 8.35 to take DS to nursery but the TV was on albeit CBeebies and the DC got dressed to CBeebies until they grew out of it. They had their first DS thingies (screens) at about 6 and the peace it gave me was bloody wonderful. They didn't just learn about pokemon: they learnt about elements (nature), "characteristics (psychology), to spell their long names and write stories about them, to win points and decide what earned more points (maths).
With a diet of reading (mythology, literature, poetry), painting, play, park, sandpit, playgroup, story time, etc, screens have their place. We loved Telly Tubbies, Auntie Mabel, Big Cook Little Cook, Thomas, Rosie and Jim, etc, usually first thing to buy me time to tidy up and get some slap on.
My DC were usually grubby, usually happy, certainly never slept 7 to 7, and were allowed sweets after tea. I recall DS stayed up to watch the early series of I'm a Celebrity, get me out of here and often wasn't in bed before 10pm (up at 6ish though). Neither needed much sleep and had me up multiple times in the night.
They started reception knowing their letters and numbers, and very much else, and were free reading by their 6th birthdays. Despite their shocking, neglectful toddlerhood, and access to screens. DS had a mobile aged 13; dd aged 11 and their own laptops aged 10/11, DS did his first degree at Oxford, DD at Cambridge.
@ILoveFatFaceSocks very gently, by all means have a coffee and chill with the TV on at 8am, but sit up and perhaps find something age appropriate. I recall East Enders coming on at 2pm when mine were little and not realising straight away. The swearing, screaming insults and physicality were so dreadful I wrote to the BBC because it was inappropriate before the watershed. It is not something a baby/toddler/child should be watching. I'm not opposed to screens - they are a significant part of 21st Century Life but it's important to be mindful abiut what is on the screens.
