Pumping
Exclusive pumping
How often to pump when every feed is pumped milk, how it changes as your baby grows, and dropping sessions safely.
Exclusive pumping means your baby gets breast milk only from a bottle or cup, and a pump does the work of nursing. It's a real way to feed a baby, and plenty of families choose it or come to it. The core idea is simple: pump about as often as your baby eats. Bodies and babies vary, so watch your own trend over any one number.
The first weeks
The early weeks set up supply, so this is when frequent pumping matters most.
- Pump about 8 to 12 times in 24 hours. For a baby who can't nurse, the ABM recommends a double electric pump at least 8 times a day.
- Include at least one session at night, ideally between 2am and 4am.
- Keep gaps to no more than 4 hours in the day and 6 hours at night.
- Double pumping, both sides at once, saves time.
- One NHS hospital aims for about 750 ml a day or more by day 14. Many people make less at first and build up.
As your baby grows
- Babies usually feed about 8 to 12 times in 24 hours in the first weeks and months. Pumping about as often as your baby drinks breast milk helps your body make about what your baby needs.
- Supply from pumping alone often dips after several weeks. Keeping sessions regular helps, and adding a session can raise supply again.
- There's no official schedule for later months. If you'd like fewer sessions once supply is steady, drop them one at a time and watch the daily total.
Pump about what your baby drinks
Pumping far more than your baby drinks can lead to oversupply, which raises the chance of mastitis. Aim to pump about what your baby takes.
Dropping a session
- Drop one session at a time and give each change about a week.
- Phasing out gradually helps prevent engorgement and mastitis.
- See "Weaning or dropping pump sessions" for a step-by-step plan.
When to get help
- A red, hot or hard area of the breast, a lump that doesn't settle, or feeling feverish and unwell: call your doctor or midwife.
- Output drops sharply and stays low for several days, or your baby isn't gaining weight.
- For a plan that fits you, a lactation consultant (IBCLC) can help.
