When did you drop to 2 naps?

Baby is 6 months old next week and sleep trained. Currently sleeping 7.30pm-7.30am with 1 night feed around 4am. I struggle to keep to exact wake windows as we are often out and about and she isn’t trained for naps yet. Our schedule is usually- nap at 10am for 1 hour Nap at 1.30 for 1 hour Nap at 4.30 for 30 mins Wake windows usually 2.5hrs This makes it around 11.5 hours of night time sleep and 2.5 of daytime.

Should I drop a nap as sometimes it’s hard to get the last one in but not sure she will make it till 7.30?

Should I carry on feeding at around 4am?

Looking for schedules to compare if possible and what works for others.
