Oh poor you. We stopped bf about 6 weeks ago with no fuss but then bedtimes went to shit. DS is 23mo and I too am pg and couldn't cope with the thought of a newborn and this every evening. When are you due BTW?
I started a thread about Ds's bedtime last week and have had v good results with the advice I had. He doesn't like to be alone at any time but esp. when falling asleep. So we're 'weaning' him off needing us to help him get to sleep. Four days in, he's falling asleep with us sat next to the door, no shushing or patting which is nothing short of a miracle.
We got him to choose a new teddy, a special one that he could cuddle at night time. It comes downstairs with us for milk & night garden but stays in the cot the rest of the time, so he's part of the bedtime routine. We read bedtime stories to teddy as well as DS, kiss him goodnight etc.
I usually get asked for mummy cuddles 50 times when settling him so I told him to cuddle teddy instead. He also asks for his tummy to be rubbed, I got teddy to do this too.
It's worked very well so far- which I'm finding hard to believe because he's never had a particular favourite toy before.
Always takes them longer to settle when overtired- does he still have a nap in the day?
Does he have a nightlight or can you leave the door open for him so he can hear you in the background?
Have you tried changing his bedtime routine- making it longer/shorter. Eg, you could take him upstairs earllier but spend more time doing stories, cuddles and songs before you say goodnight?
You could stay with him for now whilst he falls asleep but be really firm about the fact that it is bedtime & he must stay in bed. Tell him how impressed you are with him the next day for anything that went right about bedtime, and what a big boy he is being, but don't mention the stuff that went wrong.
I'd make a plan to withdraw your presence once he's more relaxed about bedtime generally.
Others would say to get tough but taking it slowly has worked for us. Takes a while to see results unfortunately.
Good luck,hope he settles down soon.
