As a mother depending on whether you are working or staying at home, you may be deciding on breastfeeding schedules and feeding for your baby. It can get very taxing to plan when to start breast pumping and also to ensure your baby starts having a bit of solid food. Breast milk meets all the required nutrients for a growing baby especially in the first year so if you are planning on breastfeeding till 12 months then make sure you are preparing a schedule to meet the different feeding sessions.

It is important to remember that while you have introduced solid food to your toddler, it can only supplement the breast milk and not replace it until almost 2 years. If you are working, it can get demanding to breastfeed, and you might be tempted to cut down so prepare a schedule so that your 31-week old baby will not be fussy and get proper nourishment.

If you have also introduced formula milk to your baby, then you can create a schedule to ensure that you give a mix of breast milk, formula milk and solid foods. Take a cue from your baby and keep feeding until they decide to wean off the breast milk.

No matter what your feeding style is it’s important to always offer milk especially breast milk to your baby first before solids so that he/she can get complete nutrition

Another simple game you can play with your toddler is to clap. Clap your hands together, and your baby will start mimicking you. You can even start singing some nursery rhymes to them as at this stage your baby is starting to recognise sounds and make associations. Another great game for your toddler is hiding his/ her toy and encouraging them to find it. Usual hiding spots can be under the blanket so that your baby is delighted when he/she finds it
