2 Year old - Putting to sleep now new baby on the scene

I would love help!!!

My toddler (turned two last Friday) has had one sleep in the day at midday for 45min-1.5hrs . I lay with him to put him to sleep (if he did not fall asleep in the car on the way home).

Then he had bedtime routine of dinner at 5pm, bath at 6.15, into bed and Mummy lie with him and was asleep by 7.30pm.

He sucks thumb and twirls my hair to put himself to sleep. He has a stuffed toy (doggy) the he also cuddles.

This routine worked until baby Sophie came home and now (two weeks since Soph has been home) he is extremely naughty re sleep. In a word, he flatly refuses to go to sleep!!!!

Since last Friday night we have not been able to get him to sleep by lying with him in his own room - last night he fell asleep on the couch with me watching tv at 8.15pm, the night before in bed with me at 10pm!

Today, he flatly refused to go to sleep at lunchtime - and he gave me very cheeky faces. I ended up getting him to sleep by going to the shops and he fell asleep on the way home.

Questions - I don't want to used controlled crying - never have - but what do I do??? Just before xmas I got him into his own bed in is own room - he co-slept with me in my bed from 9mths - 15mths...then on a mattress beside my bed until xmas time...then he moved into his own room and own bed (which he did with no fuss at all!!!). From birth until 9mtns he slept in his cot in his room (until sep anxiety started just as I returned to work). Hence, I have never used control controlling...but I need to do something...He is now ruling the roost!!!! I admit it but don't know what to do!! Especially as I am exhausted with a newborn who is feeding every 2 hours!!! (she is only little).

If you have a two year old, do they still daysleep - wondering if I should be dropping it???

Also, what time do they go to sleep at night???

It seems like all the hard work, I put in the get him ready for this baby (sleeping in his own room with no fuss) has gone out the window.

Please, would love advice!!!!

Oh - have moved baby into my room in a basinett so that her crying doesn't wake him in the night! This has helped - so he can't come back in with me really as an option!
