Hey mamas, 8 months PP and around 4 weeks pregnant (I hope) got a positive two days ago.

I have an 8 month old daughter and I’ve just found out I’m pregnant again which would be our second baby. If everything goes to plan is anything different with your second baby as in whooping cough vaccine etc at 12ish weeks as I only had it last year or do you have it again? Makes 0 difference to me I was just curious what people’s experiences were after having 2 under 2!
