Anyone else’s babies super clingy? 🙄

So I have a 4 month old and he wants me to hold him like 24/7 and screams bloody murder when I put him down so I just let him cry for about 5 minutes before picking him up again and my family judges me for letting cry but I let him cry for a few minutes when I know there’s nothing wrong with him and that he just wants to be held.. like I have shit to do I can’t be holding him 24/7. I have one of those baby carrier things but I can’t figure it out for the life of me , and when someone put it on for me my baby was sagging so low in it so I don’t feel like it’s safe. I want my son to learn to entertain himself and that he doesn’t need me all the time, what do I do? It’s driving me crazy . Also if you’re gonna be a judgemental bitch don’t even comment 😁
