Being considerate

So my husband wants a baby and I told him we have to wait until after November to conceive because my boys birthday is July& August. I told him that is inconsiderate to give birth to a baby right before or even during the month of one of my kids birthday. He doesn't think so saying they will get over it sir they are 8&4. I don't want their birthday being overshadowed by a baby it's bad enough they have to split my time. Is it wrong to make him wait? I even told him I'll get on birth control to make it not happen and he got mad instantly. It's been 1yr and 7m trying for a baby.... I'm over the whole having a baby thing but my husband doesn't have any😔 He knows I was joking about the birth control thing. I haven't been on it years. I just need a break in ttc I'm tired. I never said I didn't want a baby I just don't want it being the same month as the kids I already have. I want my new baby to enjoy their birthday in peace as do my other kids. Y'all completely misunderstood what I said....
