Hi L.!
I just posted a responce to another mom with sleep issues. The advice I gave her will work for your two year old also, so I'll just copy & paste it, with a few changes due to age differences in your babies.
By the way... I fed my, now, five year old from a bottle until he was ready to switch to a cup, which was at age four. He has perfect pearly whites and no dental problems.. (But he's been brushing his teeth since age two, no toothpaste of course & didn't eat much sweets..lol) so don't believe all the hype about bottles. Below is the advise for getting a good night's sleep. Hope it helps! :O)
If I had followed the advise of the baby books, I could've saved the family alot of sleepless nights. So, on child #3, I finally did what the professionals advised & the benefits were well worth the few weeks it took to get there.
Step one, You have to let the baby cry herself to sleep. So be prepared for some tough moments on your heart-strings..
Step 2, Get into a ruitine of feeding your child her last feeding & then having something like a bath or singing or a radio playing lulubies that will teach your child to calm down & expect to go to bed. (I stood & rocked my baby while singing 3-4 songs.) Make sure your baby is AWAKE when you put her in her crib/bed. Make sure her diaper is fresh, & since you just fed her, she should be good to go.
Step 3, LEAVE the room, (after you kiss & say good night.)
Step 4, if the baby cries wait for 2 minutes before you check on her. Walk in the room, check her diaper, if she's dry, say goodnight & leave the room.
If she continues to cry wait five minutes & walk in, check her diaper or burp her & leave the room.
If you're sure she's not sick, wet, or has a gas bubble, then do not go in the room anymore.
Use a monitor to hear her, & she may cry for 20 minutes the first few weeks before she goes to sleep. That's OK.
Step 5, if she wakes up crying, don't rush to feed her. Give her 5-10 minutes to see if she'll go back to sleep. (That's the hardest part.) Check in on her for wet diaper if she continues to cry, but then put her back in bed without the bottle. (I gave my son a stuffed animal for comforting, and a pacifier..)
I breastfed my baby for 6 months, & by the forth month, he went to sleep at 7PM and woke up at 7AM. Plus he took a three hour nap in the afternoon. (using same steps to put him down awake in his crib...) (He was adorable amusing himself & talking to himself in there as he got himself to sleep.) & I think that helped him to learn to entertain himself, because he plays well & is very imaginative with his toys now. He is now 5, robustly healthy & very smart. Early walker & talker. Not to mention loveable & secure, so don't think that doing these steps will damage your baby, (like I did with my fist 2..lol)
Good Luck!! K.
