Any tips on back to back

Aged babies my son will be 1year old when the baby is born . I just recently found out I was pregnant at 22 weeks . & have been braking my head about how it’s going to be to have 2 small kids running around my other kids are a lot older 10 & 7 my step son is 9 ... but just wondering what stroller are you mom using how naps consist & last the BIGGEST reason why I’m scared is making sure my 1 year old who is right now 9 months old doesn’t feel loss of attention & love because that’s the main reason I did not want to have another baby until he was a little older . I just want any advice tips from mom’s who have little ones close in age .. I have this feeling that I will not be able to love this baby like I love my 9month old right now ....
