I am a person who loves structure and routine
So do I! You can create some routine, just in a baby-centred way. But definitely having structure to your day helps, I know it helps me.
Imagine you have another child in 5 years time. At that point you will have to get baby up at a set time because you'll have to get older sibling to school on time. Likewise your older sibling will no doubt have structured meal times, you'll need to fit naps around the afternoon school run.
You lack that structure in your day now because this is a first child. But you can definitely create the routine and structure if you want to. Baby will probably thrive on it. But the caveat is, you need to be realistic in your expectations.
Do first - set your alarm and get yourself and baby up at the same time every day. This includes weekends (although your partner could share early get ups).
7am is a good idea, but whatever works for you. If you're the sort of person who likes 10 mins in bed before you get up, set alarm for 6.50 and get up with baby at 7am. If baby is frequently waking earlier than that, you'll need to set your alarm to match I'm afraid. Routine means you making it always the same - 7 days a week, 365 days a year.
On from that, at 10 weeks old rather than having naps by the clock, have naps in a regular and predictable cycle. To get your routine, you routine the awake time to always be the same.
A good idea for cyclic routines is EASY:
E - Eat - Feed baby as soon as they wake
A - Awake time - st this age that will be floor time under the playgym or tummy time. This is where you clock watch for routine. You have a set amount of time between baby waking and going back to sleep. It takes a bit of tinkering to find the right awake time for your baby buy at 10 weeks I would expect it to be about 40-60 minutes of awake time.
S - Sleep - Notice the time baby last woke up and make a mental note that in 40 mins time (or sooner if you get any crying) you are working on resetting baby back to sleep so that baby is asleep within 60 min of last waking. Or alter the timings to suit your baby, but do the same timings for every cycle.
Y - You time while baby sleeps.
When baby first stirs awake, try to resettle back to sleep. But if baby isn't settling then that's your awake time again and you start the cycle again...
Wake... Feed.. Set length of time awake... Sleep... Wake... Feed.. Set length of time awake... Sleep.. Wake... Feed.. Set length of time awake... Sleep...
Repeat repeat repeat through to bedtime.
