Need advice on my husband

Back story: I’ve been with my husband for 9 years. We are best friends. I have a nearly 9 month old son and am 18 weeks pregnant and due in July. I’m also a childcare practitioner profession wise. Lately, I’ve been feeling like I do absolutely everything all by myself with next to no help from my husband. I do all the washing, cleaning, cooking meals and looking after our son. I find that he doesn’t take much interest in playing with him, he doesn’t take initiative to make him dinner or put him down for naps. I’ve done bed time ever since he was a newborn and his excuse is “he goes down better for you”. I also feel like he thinks because my job is looking after children and has been for the last 10 years that he thinks it’s okay for me to do it all by myself. He wakes up at 5:30am every day to go to work and gets home around 3/4pm most days, goes for an hour long poo where he just sits on his phone watching TikTok’s and then comes down and falls asleep on the sofa, bearing in mind for a very long time most days. I’m just really struggling because I feel like if it’s this bad now then it’s only going to get worse when I have two kids to look after. I’m also not going back to work yet so I will be off every day with 2 under 2. I have spoken to him about this and he says “I’ll change” bla bla bla but it’s just not happening.
