My baby doesn’t sleep through the night anymore. He is one in a few days and for the last few months he's been waking up at least twice for milk, or just randomly crying. He used to be a really good sleeper so I don’t know why he is like this now.
Any advice and explanation for why he is like this?
Hi my little girl did exactly the same when she was about one. Look up sleep regression. It can be because they are learning so much at this age it affects their sleep.
