kids close in age

Veronica • George Alek Jr 4/08/17💙 Layla Jae 8/16/2018💜 Currently pregnant due in November

My son will be 5 months on the 8th. I will be 26 in October. My husband and I are only using condoms for protection. I don't want to be put on birth control because I don't like the side effects and because we eventually want two more kids. We want our kids close in age like 2 years max but if it happens sooner we wouldn't be upset either. But I just want advice or opinions from mom's that have theirs kids close in age and how y'all manage lol
