Advice/opinions? Baby #4

Jane

So I know this is a personal decision that I’m going to have to make but I just want to see other’s opinions. I just had baby #3 on May 31st , my older two are 5 and 7. I want one more but not for a few more years but my husband hasn’t been wanting another. Well he told me today that he wouldn’t mind having another but he wants to have it asap if we do. Like within the next year. I plan to breastfeed this baby for at least 2 years. Idk how I feel about having 2 little babies at once, it was already hard when my first 2 were only 2 years apart. I can’t imagine them only being one year apart but I really do want at least one more. Any advice from someone who has babies so close in age? Also, any mamas that breastfed 2 at the same time. Was it worth it or would you suggest that waiting longer?
