you're not alone and you definitely shouldn't feel guilty!!

my DD1 was a dodgy sleeper from day dot. DD2 has been a sleeper from day dot. she was terrible during the day but come night time she consistently slept 9-13hrs. whilst it has changed a bit since she turned 2 in Feb she still sleeps approx 10hrs. she does sometime wake 1-2 times a night but a pat and shhh and she resettles.

don't feel bad just consider yourself "lucky" - that's what i do!

eta: if ppl ask about my kids (moreso DD2) i do tell them that yep she likes her sleep but not in a "braggy" way. i also don't take to heart their response (if it's negative) because i think well who knows where they are in their journey and i try to comiserate with them because my DD1 didn't like sleep so I've been on both sides of the coin.
