I have some advice for you when you get a new sibling. Getting a new sibling can be very hard for the one – the only child – that you already have.
Our oldest son was two and a half years old when he got his little brother, Victor. And especially when I was breastfeeding, this was the time of the day when he started making all sorts of jokes, he ran around, he threw things, he was really taking his liberties when I was stuck with Victor.
So then I though, "What can I do to keep Oscar, the oldest one, quite close to me and also to make breastfeeding something funny instead of something terrible?” So we got this little box with things that were only for old children, like for Oscar. And I took it out every time that I was breastfeeding. And it almost became like a fun event for him.
So each time he said, "Now it's breastfeeding." He came running instead, because he wanted to see what was in this box. And then we sat there and we played for the 10 or 15 minutes that it took. And then it was a nice period during the time instead of a horrible period of the day.
