So my little girl 17months old

Her routine is for her to have her tea a little play a bath and then bed she won’t go to sleep unless Me or my partner is the room we have to sit with her untill she is asleep ... she usually goes to bed between 7.30 and 9 depending what time she gets up she also doesn’t have a nap or she stays up until a ridiculous time at night...

she still needs a bottle to go to sleep with but also she will wake up in the night for more milk iv tried to swap it for water but she wont always go back to sleep without it should she still be having a bottle through the night? Also if I sleep trained her will she stop waking up through the night?

She doesn’t always wake up sometimes she will go sleep at what ever time before 9 then not wake up untill 10 the day after then some Nights she wakes up 3 times how can I stop this from happening?

I’m pregnant with my second baby not due untill may next year but I want to sort this sooner rather than later

Thanks in advance

And pleaseee no horrible comments this is meant to be a friendly place for advice!!
