I can totally relate to your post FL when I had DD1...

She was, from the get-go one of those crazy kids that just loved to sleep. i could take her anywhere, do anything and be totally 100% confident that she would sleep well and long. She was easy to put down for naps and would do 2 or 3 2-3 hour naps until she was close to 18 months

At first i just assumed that it was because i was an awesome parent raising a totally confident and self-assured kid (which i am of course and she is of course pmsl!), but then DD2 came along and threw alll of that out the window. she was a shocker and only started to sleep through the night at around 20 months...and stopped all semblance of day sleeps at about a year.

DD3 is kind of inbetween. she was, for 2 months a fantastic easy kid to get to sleep and stay asleep and i had a blissful couple of months of full nights of sleep (without hassle put her down awake!). But then she hit the 4 month sleep regression and we are on a total rollercoaster. she is still easy enough during the day but nights are pretty rough at times (in that she wakes often...thankfully all it takes is a quick BF each time).

But yeah, with DD1 i quickly realised that one does not mention ones 'good' sleeper i think it makes all the sleep deprived people out there want to weep ('cause i think i feel like weeping thinking back to all that glorious sleep i had with DD1 hahahahaha).

Also, i reckon that (and this from my own experience) people with kids that sleep easily etc they just dont talk about sleep that much either...because, seriously, what's to discuss IYKWIM. i remember being gobsmacked at mothers group how each session was dominated by 'sleep' talk. i couldnt understand how people were so obsessed...i didnt get sleep deprivation back then: I was still a new mum and was still tired so thought they felt like me...i just didnt realise how catatonic sleep deprivation was ITMS.
