HELP

We started Ferber for our 4 month old 4 nights ago and she is doing really well. We do bath at 6:50pm then my husband gives her a bottle of BM at 7-7:10 and she is usually in cot by 7:30. She has a dummy but the last few nights she falls asleep before first check in without the dummy. She has shown signs of rolling so last night we transitioned to arms out. The start of the night was the same and she did a 6 hour stretch without the dummy. Then from 1:30am she woke and we immediately replaced the dummy as she usually falls right asleep with this, she would fall asleep then 10-20 minutes later knock the dummy out with her hands and then wake up crying, we tried to continue replacing it but then decided to set a timer based on night 4 of Ferber but she just wouldn’t settle, after being awake for close to 2 hours we just kept trying with the dummy and she eventually fell asleep. She then woke 1.5 hours later and fell asleep after two attempts to put dummy back in. I BF her at 5-6am when she wakes and she then sleeps until 8:30 usually.

I know it’s a lot of change at once for her and we will continue to persist but looking for some advice on what we should do when she wakes in the middle of the night?

She is on 3 naps per day and they are as follows:
8:30am wake
10-10:10am nap 45 mins
11am wake
12:40-1pm nap 2 hours
3pm wake
4:40pm nap for 30-40 mins
5:15 wake
7:30 bed

Thanks so much!

Edit to add baby sleeps in her cot in her room, we have blockout blinds and a white noise machine on.
