What age did your child drop to 1 nap?

[Findahouse21]

Can you please tell me what age your child dropped to 1 nap, especially if they were quite early to do so? Dd (8 months) has always been a terrible napper, but seems to nap better when having only1 nap. If I force 2 then sometimes she won't have 2nd at all, so her daytime sleep is only 30 minutes total, whereas if I let her have a later nap she'll only have 1 but it can be up to 90 minutes.

Thanks everyone. I'm definitely going to go with 1 nap as it's so much easier than trying to force 1 out of her. Even though she's my second I was just doubting whether it was too early, but you've reassured me! She gets a decent amount overnight, usually going from 7:30 - 8, albeit with 3 feeds, so I don't think she needs to nap as uch as her sister did who was a champion napper
