15 month old sudden regression and separation anxiety
Hi all. Our 15 month old has slept through the night since 10 months, sleep trained and removed bad associations etc. Used to go down peacefully absolutely 0 refusal and the whole process would take 5 minutes.
Now all of sudden he starts getting upset as we start the bedtime routine, refuses to drink his milk and then cries standing in his cot. I manage to get him to sleep by sitting by his cot and eventually laying him down and putting my hand on him. He then wakes up in the early hours and I have to go in and resettle him, if he hears me leave at all he'll be back up.
A few times I've given in and brought him to our bed so we can all get some sleep. I just need to know if this is a phase and some co-sleeping won't cause a long term association, or if it's reset his ability to sleep independently and I need to redo the sleep training methods?
Thanks in advance for your tips and experience
