My DD is 20mths and very very rarely sleeps through, like she's done it maybe....6 times in her life (at home, when we sleep at nana's she sleeps through often.....). She's going through a rough patch at the moment and we can be up more times with her than with DS, up to 6times a night! DS wakes probably 3 times for a feed, he's cosleeping and doesn't often get to cry before I shove my BB in his mouth, LOL! So I haven't had the issue of him waking DD (she's in her own room in her cot). DD doesn't usually wake DS, though sometimes he will wake after she's been screaming, or woken at night.
Yes, it does get better. But they are all different, and TBH, even once they start sleeping through, there are always some nights when they wake - be it illness, wetting the bed, nightmare or whatever.
DS1 slept through every night from 6 weeks until 7 months. Then we had horror nights until he was 16 months. DS2 started sleeping through at 12 months, and is now the one who is least likely to wake in the night.
So there is definitely light at the end of the tunnel. FWIW, DS1's sleeping was at the shocking stage right up until 3 months before DS2 was born. But luckily he did settle down before the birth.
I should also say that when DD was a newborn and during those first few months, she wasn't woken by DS. It's only as she got older and more aware that she's become a lighter sleeper.
Actually, it's only been on the very odd occassion that either of my boys have been woken by the other. DS1 is a lighter sleeper than DS2, but I think they are both so used to each other's sounds that they even sleep through loud crying most of the time!
