Hey lovely!
My little boy is 4 months tomorrow, we have really got into our stride the last few weeks. The main reason has been teaching him to self soothe! I am not a beleiver of letting them crying it out as that breaks my heart so i opted for my own method of a few different ideas and it has worked well.
I follow my usual routine of wake window, bottle, swaddle, dummy and rock then I put him down drowsy. If he cries I go straight in and pop dummy in, if he closes eyes and settle I leave him, if not I rock again to sleep. This has beeb a game changer!!!
At night, I keep him awake from 5pm to 7pm, around 6.30pm I bath, lotion, fresh jammies, swaddle, story, dummy, rock to sleep! He goes down by 8pm , I dream feed at 10pm and he either sleeps through to 6am or wakes once.
We also do something we call the dummy reset lol! If he's upset whilst soothing we take dummy out, let him have a little 10 second cry then pop it back in, it sounds ridiculous but it works.
It's all trial and error, and what works one week, fails miserable the next haha!
