My 1 and 2 year old are the exact same, down to waking up around 3 to come into my room. No advice, but here for others responses
So my 2 year old was the same at 1 year old, and still is at 2.5 years old. We bring her in to get more sleep as otherwise she will wake up every 30 minutes or so crying. Sometimes she does go back to sleep and stays the night in her bed. When she wakes up the first time I encourage her to have a drink and lie back down and go back to sleep. I don't bring her straight into our bed to try not and make it a habit unless she is really upset. If she wakes a second time I bring her into our bed so that we can all get a good night sleep. The reason I do this is we have the room in our bed and we also have a newborn so don't want to be anymore sleep deprived than we already are hah! And they also say thst you never see an adult that is still sleeping with their parents because they never learned to sleep in their own bed! It could be a regression or teething at this stage. There is so much going on in their tiny bodies and they can't tell us what is going on.
Things I also tried just in case it was something else: Calpol before bed in case of teething pain. Took out the bottle to sleep and had it 30 minutes before bed. This helped improve night sleep. Gave porridge/weetabix (filling food) an hour before bed to fill them before bed so not waking hungry or looking for a bottle. Bath as part of bedtime routine to encourage sleep.
Commenting so I can come back. I’m struggling with the same. My son falls asleep in his bed and wakes up around 2 calling me to come get him. The only time he’ll spend the whole night is when his dad sleeps in his room on the floor.
