I've just had my little boy. In hospital we were feeding with the Aptimal ready-made formula bottles. Got home and started on Aldi's Mamia. We made the first feed with our kettle at 5pm and our prep machine at 11pm. This is what his poo is looking like now. Is this normal? It looks quite chunky... we have fully shaken the bottles to mix the formula. He does seem to be straining a little too. This is the second dirty nappy since coming home at 5pm today.
