Dd2 is 2 and in the pram as often as possible. It is mostly when I have her on my own ad I find it easier to control her & Dd3 like that. I have a Phil & Teds Vibe which is awesome because I can put the toddler seat on the front whilst DD2 walks around and when she gets tired, I move the toddler seat to the back so DD2 can the sit up front.
As for toddler beds etc, DD2 went into a toddler bed at 20 months and I personally think she was too young. She would get up through the night and wander around the house rather than sleeping and she was too little to understand why she couldn't wander around. The cot was definitely best for her. Now, she sleeps I'm the cot that has the side removed and is against our bed. We co sleep with her & Dd3. Crazy stuff. We're going to try putting her back in her bed this weekend, so fingers crossed she loves it this time around.
