@Husbandno4 It is clear that different parents have their own way of doing things and beliefs about nappy changing.
But, the most important thing is that you and your wife do what feels right to you both. Don’t force the other into doing or giving in to something that makes them feel uncomfortable even if you think you are right.
Having a baby brings lots of changes and challenges to parents (and siblings) lives. There’s sleep deprivation, recovery from birth, emotions, unknowns, learning curves.
Having a baby can test a relationship between partners.
Disagreeing over whether to change baby’s nappy after every wee and getting into a I’m right, your wrong is going to put additional stress, that you don’t need, on your relationship.
If it is something that your wife feels is very important for baby’s comfort and wellbeing, does it really matter if you don’t agree.
Would it really make it harder on you to just go ok, I respect that it is important to you (even though I don’t think it’s necessary) and just change the baby’s nappy if it’s wet. It won’t harm you or the baby to change the nappy more frequently than you would otherwise if it was just left up to you.
The important thing is that you are a team, who love, respect and support one another.
Mum is recovering from birth and bonding to baby, baby is learning to adjust to being outside of the womb (read about 4th trimester) and bonding with mum and dad, Dad is bonding with baby and adjusting to all the changes and supporting Mum who is still recovering. Both parents are sleep deprived and adjusting to their new lives and how it impacts their relationship.
Go easy on each other, support each other, and communicate with each other.
Just don’t get caught up with disagreements and proving the other parent wrong, or wanting one side to win.
Both parents will have their own parenting style. That’s ok. Find what you both agree on. When you disagree explore compromises that work for both of you. When appropriate give each other the freedom to do things in their own way (unless it disrupts baby’s routine or causes distress for baby or is unsafe etc).
Never undermine each other in front of the children. They will love you both equally, look up to you both equally and it will create anxiety, confusion and behavioural issues if they see either of you undermining the other or overruling the other in front of them.
Becoming parents can make or break a relationship. Work on being a good team, that has each other’s back and loves each other.
Congratulations on your new baby
