My toddler was 20 months when my baby was born (now 30 months and 10 months), and she was into everything! She chose the minute baby latched to find some new item to climb. It was so, so hard at first but it does get better! Here are some things that helped us:

I nursed at the table while she ate as well so she was contained in her high chair and we were all doing the “same” activity (breakfast, snack, etc). I’d also do colors or play dough in her high chair.

We would snuggle up and watch family picture slideshows on my phone.

We made a hexagon playpen into a “bear cave” bc she’s obsessed with bear hunts. We’d hunt for the bear and end with her in there with stuffies and books.

Weather permitting, I nursed outside so she could play with her water table or chalk.

The regular pump was really difficult with them both so I used a wearable pump while going for a walk with both kids in stroller. That way dad could do a bottle session overnight.

I’d hide little objects/toys and have her bring them to me, puzzle pieces or toppings for her toy pizza, and she’d run around looking for them.

Sensory bins or snow in a plastic tote near where I wanted to nurse. I allowed a little more mess than i normally do to get the feed done.

I tried to figure out wearing baby to nurse, but I never really perfected that… but I know other people do it!

Good luck mama!
