By 'adjust', I mean get over the worst of sleep disturbances, tantrums etc.
It's early days here - DS2 is 10 days old.
DS1 is 2.9 y.o. He's been awake for long spells in the night (usually 1.5 hours) every night bar two since DS2 was born.
We have also had lots of tantrums, food refusal and extreme fussy eating (rather than pretty fussy eating).
He is shattered and fraught, and I am shattered and fraught. The only real positive is that he adores DS2.
Can anyone give me cheering anecdotes about this passing soon, or should I be preparing for another 6 months + of it?
