Recently my 1 1/2 yr old son has developed a new habbit. He goes to bed with a cup of milk. Once I lay him down I hear it being thrown. After a couple of minutes of letting him cry I go back in to give it to him. He lays back down fast I give it to him and we repeat the cycle. It doesn't matter how tired he is, he'll do it most of the time. It's been going on for about 2-3 weeks now. I get fustriated and Daddy goes in there and has to rub his back to get him to sleep. We've never had a problem with him going to sleep. I don't want to make this a habbit for him, although it seems to be getting there!!!
Don't give him the cup...if he needs a drink do it before he goes to bed. He's playing a good old game of get mum and dad wrapped round my little finger and winning hands down
Why don't you try getting your toddler to drink the milk whilst you read a story and then when you leave the room it's lights out with no distraction. If he/she has not finished the milk by the time you have read the story then it is obviously not needed and is removed when you leave.
I totally agree with Ellie on this one. Your son is really young so there is a chance this can be nipped in the bud. My son is 4 this month and once he's in bed all he does is call after me and his dad. We give him a kiss and a cuddle and that's it. After about 5 minutes of calling us he gets fed up and goes to sleep.
