My daughter will be 3 when this one arrives and I'm not going to buy a double. She won't use the pram. Deffo going to get the buggy board just incase. If she acts up to get in a pram I think I'll just use a baby carrier for the baby. And then when out with my husband I'll just bring the yo Yo for her just incase. She will be at pre school 4 days a week from September,, so pushing a double buggy around for no reason seems pointless to me! Maybe try the John Lewis baby day and take him with you? Can try out all the prams then xx
2yrs 11 months between mine and we did buggy board. Worked out great for us (we took buggy everywhere and he didn’t like to walk) now 10 months later he walks everywhere and we no longer bring buggy board.
I have a 2.5 year gap. When baby was small, I used a carrier for baby with toddler in the pushchair. As he got older, baby went into the pushchair and I used a buggy board for my older son, though I keep the carrier underneath the pushchair for those days where my older son (who is now 4) is tired and wants to sit down.
