hello bees who have sleep trained, would you kindly tell me if I am on the right track with this sleep training plan below.   I have bought and read too many books on baby sleep and  It's all jumbled up in my head.

A little back story/ context: lo is 5 months old and has always been a poor sleeper. However,  the past 2 weeks , she has gone from waking up 4-5 times a night to 8-10 times a night. I had heard about the 4 month sleep regression, but I didn't realise how bad it would be. 

I nap trained prior to the regression and she was putting herself to sleep for naps for like a week. Then all of a sudden she just wouldn't do it anymore. 

Sleeping arrangements: currently co-sleeping (we are staying at my mom's place for the next month), but there is another room that I can sleep in to end co-sleeping.

Plan: for day time naps, I plan to nurse,  read a book, cuddle for a minute and then put her down.  Let her cry it out with checks at 2 minutes, then 10 minute intervals after that. When I go to check on her I plan to shush and pat her on the back a few times,  then walk out again. Sound about right?

Question: what do I do if she then wakes up early from a nap,  say after only 30-45 mins and doesn't seem rested?

Night training: l plan to do the same as nap time (preceded by a bath, lotion,  pj routine).

I plan to feed at 4 hour intervals.

If she wakes up before 4 hours. I will let her fuss/ cry at 10 minute intervals.  Does that sound about right or should I Ieave her a bit longer,  say 15 mins of hard crying?

Also,  keep in mind that I will be doing this all by myself day and night. I have a 10 day window when I am alone with lo in the middle of February, and that is when I plan to do this.

Thanks in advance for your input. My baby and I getting no sleep and so I appreciate any tips to help this training go well.
