Hmm
DS: From about five weeks slept from about 11.30 until about 5.45. And then we tried to get him to go down at 8ish and sleep until the morning. Ha, ha, ha, ha. It took us at least a year to realise he didn't actually need much sleep and that if we didn't want him up between 2am and 5.30am it was best to put him to bed when we went to bed. This was his pattern. He never needed to be asleep before 10.30 and was always up in the morning. Sometimes at bedtime I was near to tears because my mouth used to hurt from anwering questions.
DD: Ah, never the horrendous hours of up all night romping round the room and learning letters and colours in a most precocious way. Always has needed a bit more sleep than DS - like being in bed by 9pm and waking at 7 rather than six! But I don't think she actually slept through until she was about 4 or 5 and as a baby could wake at least three or four times.
Am also adding that both of mine had awful ears from about 7/8 months and I mean ear infection after ear infection, possibly as many as 10 each. DS grommeted at 15 months (and never looked back); DD at 20 months (and never looked back). I remember a horrid patch from early December through to late March with DD where I don't think I got more than two hours sleep lying down because the only way she would settle was upright in my arms in the nursing chair.
I don't think I had many unbroken nights for about eight years.
Eventually OP they turn into teenagers and when you are lying in bed with your phone under your pillow texting your DS who is waiting for the night bus on his own in Lewisham and you are sick with worry you will dream of those days when they were keeping you awake in the night but safe behind their cot bars where no harm could come to them.
Sorry - hardened old gimmer emoticon required.
