My LO is 15 weeks and for the past month, his night sleep has completely regressed. Last night I was up 5 times to settle/nurse him. He goes to bed at 7pm and has a very solid day nap routine etc. Anyone struggling recently with their nights?!

He can’t self settle yet, I normally have to rock/nurse him to sleep. We have started sleep training and getting him to self settle but it is a long process full of tears as soon as he is put down. Anyone got any tips?!
