Hi, welcome again to BW.
Good to see you are finding your way around
Could you post your routine, how it looks for a full 24hrs. It doesn't matter if it changes every day just post what actually happened on one or two days so we can see the bigger picture. If he began his sleep in your arms and then you transferred him to a crib/other sleeping place see if you can add a brief note of what time you put him down too, and if you were able to get him back to sleep once he woke.
Post your EAS times like this for example:
7.00 WU and E
A 7 - 8
S 8 in arms. Transfer to crib 8.20. Woke 8.30
A 8.30 shush/pat in arms
S 8.50 - 9.30 in arms
E 9.30
...and continue for the day and night
Could you also give us an idea of how you help your LO to sleep? Are you using shush/pat? Rocking? Are you feeding to sleep?
I remember how exhausting those early days are. Hang in there, it will pass!
