Going from 2 -3 ?

Ok so I’ll try to keep this short. I know ultimately it’s up to myself and my husband to decide but looking for thoughts and experiences from those of you who have gone through it.

I’m 44. My husband is 12 yrs younger and is an active duty pilot in the army. We have a 3 yr old and a 16 month old.

I have the worst baby fever and want to try while I still can for our last baby. Having said that I’m very torn. Our two girls aren’t in the easiest phases of life right now. Teething , sleep regressions , jealousy, separation anxiety.. so it’s rough for us. I also have some medical issues that need to be addressed..

Am I crazy for wanting another so badly ? How hard was this transition with ages so close together ? Should I just count my blessings and close the baby making chapters ?

Any insight is appreciated!
