Hey OP. The way I managed my days may not suit you or match your parenting style but I thought I'd share my method with you.
Firstly work out when you need your baby to nap... 11am/11.30am/12pm in order to get them to wake for afternoon pick up. Then work backwards as to what time you need them to wake up in the morning. So 6am for an 11am nap, 7am for a midday nap etc. only you know your baby and their requirements. As mine always woke between 5.30-5.45am (sometimes 5am) it was very easy to get them to sleep at midday. Even now if my 5yo wakes before 5.45am she is ready to nap at 12.30pm. But if she wakes at 7am she won't nap.
So for example you need your baby to nap 11am-2pm so you need to wake her up at 6am. So for 10 days straight try to follow a fairly strict pattern to your days (even on weekends). Wake her at 6am, and as she is still a baby she might get really tired at 10 ish... Try and stretch her out for 10-15min. Make sure she is full with a good milk feed and maybe solids then start your wind down bedtime routine. For naps I used to and still put my kids in PJs, sleepy music on and feed/pat them to sleep. Or however you put your kid to sleep. The point is not how you get them to sleep but rather that they sleep at that time and set their body clock to that.
Body clock is quite interesting in that it only takes 2-4 for the body to get used to a new pattern. Think about how ppl struggle to wake in Mondays after a weekend of sleep-ins.
So after a few days of Bub sleeping at that time, you can then slowly add a particular nap routine as their body is expecting to sleep at that time.
Now this method may or may not suit your family or your parenting style. But it did work for both my girls and I will probably use it next year as well.
