Help with sleep 😴

My LO has always been an early riser but recently we’ve been up regularly at 5am and he has started getting up in the middle of the night and coming into our room. His stair gate doesn’t contain him anymore, we have a gloclock which has the sun come up at 6 and we remind him all the time that he has to see the sun but it doesn’t seem to make a difference. Finding it really hard with a baby in the house too to get enough sleep whilst also working full-time. Any advice on what to do or what has worked for you? 🙏🏽
