We moved into the stroller at 12 weeks, just had it reclined. It wasn’t even because my little girl was big, she’s only 25th centile but she just hated lying flat all the time
My boy was 15 weeks old and only 9th percentile but I changed him because he was too nosy to lie down 😂 he looks tiny in it but my pram is suitable from birth
@Katie I’m going to try him on it today, he just seems too small for it! I do find the bassinet quite narrow as well actually!x
