Newborn and toddler

Has anyone got a newborn and a toddler? Wow I didn’t realise it would be this hard! The only reason why it’s so hard is that my oldest little boy (just turned 2) will not leave my newborn alone so I can never leave them alone for 2 seconds or even put my newborn down. He’s not doing anything bad to him he just likes to kiss and play with him but will lean on him and grab his head. It takes me about 2 hours to get us ready! Please tell me that I’m not alone and it will get better 😂
