Any other mamas have babies this close in age?

So I have a 4 year old and a 6 month old and I just found out pregnant with baby #3!(im no more than a few weeks because I tested last week and it was negative but yesterday’s was positive but I was feeling so off). I can’t say my husbands and my reaction was the best, we both kinda just said fuck and I bawled my eyes out because my boys are so tiny and I’m scared of any of them feeling left out like there both still babies,I feel bad for this feeling and I hope it’s a normal first response because of course I will love this next one unconditionally and he/or she was meant to be ours. I’m just nervous like we waited a good amount of time for our last one and to think he will be a big brother makes me sad and my 4 year old literally told me no more babies but he is so amazing to his brother
