When a baby is experiencing difficulties in drawing milk from the teat, this could be due to a blockage on either the teat hole or the anti-colic vent.
Blockages may occur if there are milk residues that have built up over time or if there is excess moisture left behind during the washing and/or sterilising process. In order to unblock the teat, use undiluted baby bottle detergent to massage the anti-colic vent with your fingers as well as the teat hole as this will assist in breaking down any milk residue.

Once done, ensure that the teat is thoroughly dried before usage by gently wiping it with a clean, sterile towel or tissue (especially if steam sterilisation has been applied).
Now you are ready to begin again!
